DESCRIPTION: Brass, composed nominally of Copper and Zinc, is the most common copper-base al loy. Its uses are myriad since it is relatively inexpensive, is easi ly worked i nto any shape or form and possesses strength, toughness and good corrosion resistance.

DESCRIPTION: Si I icon Bronze is the generic term used for various types of CopperSi l icon al loys. The most common of these are Everdur, Duronze, Herculoy, PMG Metal and Olympic Bronze. The properties of these trade named al loys are all basically the same with high percentages of Copper and small amounts of S i l icon, Manganese or Aluminum added for strength. Lead is also added for free mach ining qualities where required.

DESCRIPTION: Stain less Steels are broadly defined as Iron al loys containing from 1 2 to 30% Chromium and from 0 to 20% Nickel. This analysis is further modified by additions of Carbon and other m i nor elements which contribute specific effects either to control mechanical properties or to improve corrosion resistance. The corrosion resistance of Stainless Steels is attributed to a surface phenomenon, passivity. When oxygen comes in contact with the surface it forms an invisible fi l m which protects the underlying metal from rusting and corrosion under severe environment.

BRASS CHARACTERISTICS:

Cold drawn Brass has an even greater tensile strength than mi ld Carbon Steel. I t is both tough and mal leable, qual ities that make it particularly desirable for fasteners. It is immune to rust with genera l ly high resistance to corrosion. It takes a high, lustrous finish and is nonmagnetic.

SILICON BRONZE CHARACTERISTICS:

Si l icon Bronze possesses high tensile strength superior to mi ld Steel. I t has h igh resistance to corrosive influences such as extreme temperatures, atmospheric conditions, natural and sea water, gases and sewage. It is nonmagnetic and has excellent machin ing and working characteristics.

STAI N LESS STEEL CHARACTERISTICS:

The family of Stain less Steels i s divided into three general classifications: "Austenitic" Stainless Steels make up the general group of the 1 8-8 (or 300) series. They are the Chromium-Nickel type containing upwards of 8% Nickel. They are not hardenable by heat treatment, nonmagnetic for practical purposes and offer the greatest degree of corrosion resistance. "Martensitic" Stain less Steels contain from 1 2 to 20% Chromium. They are magnetic and hardenable. Type 4 1 0 and 41 6, common fastening al loys, are Martensitic Stainless Steels. "Ferritic" al loys are also Chromium Stainless Steel al loys. They are magnetic and not hardenable by heat treatment. Type 430 is an example.

1 38

USES: Fastenings made from Brass and related al loys are widely used in electrical communications equipment, bui lders' hardware, marine hardware, a wide variety of out-of-doors assembl ies, uncountable consumer, industrial and scientific products and for general use where a rustproof bolt or screw is required.

USES: Pole l ine hardware, switchgear equipment, sewage disposal, marine applications, water meters, valves and systems, chemical, plumbing and l iquid handl ing equipment, food machinery, petroleum processing and al l applications where exposure to the elements is a factor.

USES: There are almost as many uses for Stainless Steel fastenings as there are problems of corrosion, temperature and strength. Because of its high tensile strength, corrosion resistant qual ities and abil ity to attain a m irror- l ike finish it is one of the most versati le of a l l metals. Applications include its use in the petroleum, chemical, food, plumbing, transportation and oi l equipment industries to mention just a few. Listed on page 1 3 9 are the types of various Stainless Steel alloys which are most frequently used in the manufacture of fastenings.

I N DUSTRY STANDARDS AND SPECIFICATIONS INDUSTRY STANDARDS

Most industrial fasteners are covered by two basic standards: one for materials and properties; the other, for dimensions and tolerances. Specifications for materials and properties are published by the American Society for Testing and Materials (ASTM), a lthough other groups such as the Society of Automotive Engineers (SAE) a lso publ ish specifications covering these requ i rements.

Standards for dimensions and tolerances are issued by the American National Standards Institute (ANSI) in cooperation with the American Society of Mechan ical Engineers (ASME) and the Industrial Fasteners Institute ( IFI) .

Where appl icable, publ ished specifications covering a particular fastener wi l l be referenced in the section of this booklet deal ing with that fastener.

When referring to standards and specifications, we wi l l use only the wel l-known in itials of the above societies-ANSI, ASME, IFI, ASTM and SAE.

Standard fasteners are basic industrial fasteners -square and hex bolts, cap screws, carriage bolts, plow bolts, l ag screws, studs, nuts, rivets and others - which have been standardized over the years as to type', style, usage, properties, d imensions and tolerances.

These include a vast range of sizes and types stocked by distributors and manufacturers for an almost l im itless range of appl ications: the assembly and maintenance of veh icles, appl iances, farm equ ipment, construction equipment, industrial and plant machinery of a l l ki nds, furniture and toys.

Wherever there's a need for holding parts together, holding them apart, holding them up, or holding them down, a standard fastener can usual ly be found to do the job efficiently and economical ly.

Modern industrial fasteners are manufactured to a variety of standards covering dimensions, tolerances, materials, mechanical properties, testing procedures, etc.

BASIC FASTENER TYPES

A Bolt is a device with a head on one end of a shank or body and a thread on the other end. Designed for insertion through holes in assembly parts, it is mated with a tapped nut. Tension is normal ly induced in the bolt to compress the assembly by rotating the nut. This may also be done by rotation of the bolt head.

A Screw is a headed and threaded bolt used without a nut. It is inserted into an internal ly tapped hole and tension is induced by rotation of the screw head.

A Stud is a fastener with no head but it has th reads at both ends of the shank. It, l i ke a screw, has one end that screws i nto a tapped hole. A nut is used on the other end to create tension.

If a stud is threaded its entire shank length and a nut used on both ends to create tension, it serves the function of a bolt and is then classified as a Stud Bolt.

Many variations of these basic fastener types are available.

___:t__

The diameter of a l l bolts is measured as the outside of major diameter of the thread. The length of a headed bolt is measured from the largest diameter of the bearing surface of the head to the extreme end of the point in a l ine paral lel to the axis of the bolt. For example, square or hex head bolts are measured from under the head to the end of the bolt; a bolt with a countersunk head is measured overal l . The point of a bolt is always included in the measured length.

Headless fasteners such as studs are measured overal l, including points, except for continuousthread al loy studs made to ASTM Specification A 1 93 . Th is type is measured from first thread to first thread.

Bolts have various styles of heads. Some of the more popular styles are i l lustrated above.

000 0 HEAVY HEADS AND NUTS

Bolt users may require a bolt head or nut of greater width to compensate for wide clearance in bolt holes or unusual ly heavy load ing. For such needs we offer heavy bolt heads or nut sizes. Heavy nuts are quite common and readi ly avai lable in various types and sizes but heavy head bolts have more l imited avai labi l i ty.

BOLT AND NUT BEARI NG SURFACES Cold-upset bolts made on a "boltmaker" usua l ly are washer faced but large or very long bolts may have a flat face (not mach ined). N uts made on cold "nut-formers" may have double chamfered or washer faces. Large size nuts have hot-forged washer bearing faces, not machined, un less special ly ordered.

H EAT TREATMENT Heat treatment covers various techniques that may be used t o develop certain

end-product characteristics. Customary procedures for fasteners include anneal i ng, stress relieving, case hardening, d irect quench and temper, and carbon restoration.

ANNEALING A thermal cycle involving heating to, and holding at a su itable temperature and then cool ing at a su itable rate, for such purposes as reducing hardness, improving machinabil ity, faci l itating cold working, producing a desi red m icrostructure, or obta in ing desired mechanical or other properties.

STRESS RELIEVING A thermal cycle involving heating to a suitable temperature, usual ly 1 000/1 200°F, holding long enough to reduce residual stresses from either cold deformation or thermal treatment, and then cool ing slowly enough to min imize the development of new residual stresses.

CASE HARDEN ING A term descriptive of one or more processes of harden ing steel in which the outer portion, or case, is made substantia l ly harder than the inner portion, or core. Most of the processes involve either enrich ing the surface layer with carbon and/or nitrogen, usual ly fol lowed by quenching and tempering, or the selective hardening of the surface layer by means of flame or induction hardening.

QUENCHING AND TEMPERING A thermal process used to increase the hardness and strength of steel . It consists of austenitizing, then cool ing at a rate sufficient to achieve partial or complete transformation to martensite. Tempering should follow immediately, and involves reheating to a temperature below the transformation range and then cool ing at any rate desired. Tempering improves ducti l ity and toughness, but reduces the quenched hardness by an amount determined by the tempering temperature used.

MECHAN ICAL PROPERTIES Standard industrial fasteners are manufactured from either carbon or a l loy steels.

When strength requ i rements are moderate, low-carbon steel i s used. H igh-strength fasteners are made from medium-h igh carbon

or a l loy steels and are heat treated to develop desi red properties. Most fasteners are covered by specifications that define required mechan ical properties such as tensi le strength, yield strength, proof load, and hardness.

TENSILE STRENGTH The maximum tensi le stress in pounds per sq. in . which a material is capable of susta in ing, as developed by a tension test.

YIELD STRENGTH The stress at which a material exh ibits a specified deviation from the proportional ity of stress to stra in . The deviation is expressed i n terms of strain, and in the offset method, usual ly a strain of 0 .2 percent is specified.

PROOF LOA D The point to which a material may be stressed without evidence of permanent deformation.

HARDNESS The resistance of a material to plastic deformation. Usual ly measured in steels by the Brinell, Rockwell , or Vickers indentation-hardness text methods.

SCREW TH READS TH READ FORMS

Screw th reads are spi ral grooves produced on the outside of a bolt (external threads) or machi ned i ns ide a n ut ( i nternal threads). Fou r thread forms have been establ ished by the ANSI : U N (i nternal and external th reads). U N R (external threads only), U N K (external th reads on ly), U NJ ( internal and external th reads).

CUT VS. ROLLED THREADS The terms "ro l led thread" and "cut thread" refer solely to the physical characteristics of commercial bolts or studs, not to the method of thread production. A cut-th read bol t has a sha n k diameter equal t o t h e th readed diameter; a rol led-thread bolt has a shank d iameter less than the threaded diameter.

CLASSES OF THREAD FIT Classes of th read fit are d ist inguished from each other b y t h e amounts of tolerance specified. C lasses 1 A, 2 A, and 3A apply to external threads; Classes 1 8, 2 8 and 3 8, to i nternal threads.

Classes 1 A and 1 8 are shown in ANSI standards but are rarely used. Most standard fasteners are produced with a Class 2A fit for bolts and a Class 2 8 fit for nuts. The Class 2A a l lowance assures easier assembly of mati ng parts, m in i mizes gal l ing and seizing in h igh-cycle wrench assembly, and can be used to accommodate commercia l electroplated fi n ishes. Classes 3A and 3 8 afford no al lowance or clearance for mating parts and are used ch iefly for appl ications where a c lose tolerance fit is important.

Class 5 is a special interference fit which resu lts in an actual overlap of d imensions when threaded parts are fitted together. It is normal l y used only on the tap-end of studs. Thread i ng requ i rements are designated (1 ) by the number of threads per inch appl ied to a specific diameter; (2) by the i n it ial letters of the th read standard ( U N R or U N); (3) by the letters C, F, or n umeral 8 to indicate coarse-, fine-, or 8-th read series; and (4) by the thread fit. The fol lowi ng example i l l ustrates the method of designating a screw thread:

1 /2 i n . 1 3

U N R c

2A =

1 /2 i n . - 1 3 U N RC-2A where

nominal d iameter of thread n umber of threads per i nch thread form standard (Un ified National Radius- Root) coarse-thread series c lass of thread fit

The coarse-thread series ( U N RC or UNC) is used on the vast majority of bolts and nuts. Number of th reads per i nch ranges from 20 threads for a 1 /4-i n . - d iameter bolt to 4 threads for a 4-in .-diameter bolt. The fine-thread series ( U N RF or U N F) is found mostly i n automotive and aeronautical work. Threads per i nch range from 2 8 threads for a 1 /4- i n .-diameter bolt to 1 2 th reads for a 1 - 1 /2- in .-diameter bolt. There is no fine-thread standard for fasteners over 1 - 1 /2 i n .

The 8-thread series (8U N R or 8UN) is used only for s izes over 1 i n . i n d iameter, usua l ly i n h ightemperature, h igh pressure service.

HEAVY HEX BOLT

Hex bolts are avai lable in two d i mensional standards:

H EX AND H EAVY HEX The heavy hex bolt has a head d i mension averagi ng

approximately 1 /8" wider across the flats than the standard hex bolt. It is general ly used for app l ications where maximum bearing area is requ i red.

Hex bolts are offered with U N RC-2A threads in d iameters ranging from 1 /4" through 2 " . Heavy hex bolts with U N RC-2A

threads are offered in d iameters of 1 /2" to 1 - 1 /2 " inc lus ive.

Hex bolts of heat treated carbon or al loy stee l are avai lable from cap-screw stock.

Special Note: Hex bolts in a s ize range from 1 /4" thru 3/4" in d i ameter

and in lengths 8 i nches and shorter are often sh ipped from Cap-screw stock at the Hex bolt price. However, when ordered as hex bolts there

is no guarantee that they wi l l meet a l l Cap-screw requ i rements.

TYPES OF STU DS CONTIN UOUS THREAD STUDS

Continuous-thread studs are threaded from end to end and are often used for flange bolti ng with two n uts appl ied.

Type 1 - General pu rpose. The length of th is type i s measured from end to end. Threads are U N RC-2A.

Type 2 - Studs for temperature-pressure p ip ing. These studs are made to the dimensional standard requ i rements of ANSI 8 1 6.5 and have a length measurement requ i rement different

Type 1

from a l l other studs, i .e., the length is measured from fi rst lENGTH- ''' THREAD ro '"

th read to first thread, exclus ive of poi nts. Points are flat and Type 2

chamfered. Threads are U N RC-2A for a l l sizes 1 in . and under and 8 U N R-2A for a l l sizes over 1 in .

TAP-END STUDS Tap-end studs have a short thread on one end, cal led the tap end which is threaded to a C lass NC5 or Class U N RC-3A fit. Th is end is for screwing i nto a tapped hole. The other or nut end is threaded with a Class U N RC-2A fit. Length of the stud is measured overa l l . The '---------==-"----1 tap end has a chamfered poi nt, but the nut end may have either a chamfered or round poi nt, at the manufacturer's option. Tap-end studs are avai lable in fou r types, as fol l ows: Type 1 - U nfi n ished, have a fu l l diameter but no standard body tolerances.

Type 2 - Fin i shed, having either an u ndersize body with rol l ed th reads or a fu l l-size body with cut threads, at the manufacturer's option. The body portion wi l l be fi n ished to a m i n i mum Class 2A pitch d iameter or maximum basic major diameter of the n ut-end thread.

Type 3 - Fin ished fu l l-body, having tolerances equal to that on major diameter of Class 2A threads.

Type 4 - Fin ished close-body, m i l led or ground to tolerances specified by the user.

DOU BLE-END STUDS Double-end studs have equal- length threads on each end 11\111( m to accommodate a n ut and are threaded to a Class 2A fit. � Length of stud is measu red overa l l . Both ends have chamfered poi nts, but round poi nts may be furnished on either or both ends at the manufacturer 's option. This

OPTIONAl POINT BOTH ENDS

style is furnished i n the same four types l isted for tap-end studs. Double-end studs are used for flange bolting or other appl ications where torquing from both ends is necessary or des i rable. Most steel grades not heat treated or quenched and tempered can be furn ished on special order for production quantities. Only the Type 2 continuous th read studs made to specification ASTM A1 93 grade 87 are stocked i n a fu l l range of s izes.

GENERAL DATA ON TAPPI NG SCREWS 1. SCOPE AND CLASSIFICATION:

A. Thread Forming Screws. For application in materials where large internal stresses are permissible or desirable. The following types of Thread Forming Screws may be used within the range of recommendations:

TYPE "A': Not recommended for new applications: See Type 'AB' be

low. The Type "A" Screw has a coarse pitch thread with sharp gimlet point. Primary application is in light gage sheet metal, wood, plywood, asbestos compositions, etc. I ndustry standards have obsoleted the Type "A" Screw, and unless specifically stated other

wise, we will ship Type "AB" when Type "A" is ordered.

TYPE 'AB': The Type 'AB' has the finer pitched thread of the Type "B" plus the sharp gimlet point of Type "A" which facilitates entry where hole misalignment could cause problems. The "AB" Screw is used in light and heavy gages of sheet metal, wood, plastics etc., where

frequent removal is not necessary.

TYPE "B": A Thread Forming Tapping Screw with a finer pitch thread

than Type "A". This fastener has a blunt point and split lead thread to facilitate driving. Type "B" screws are recommended in heavy

gages of metal, castings, both ferrous and non-ferrous, plastics, etc., where removal is not a design criteria.

TYPE "BP': A Type "B" Screw with 45-degree included angle cone point. The "BP" Screw is particularly suitable in light and heavy gages of

sheet metal. The cone point facilitates entry where there is hole misalignment.

TYPE "C": The Type "C" is characterized by machine screw type threads. It is intended for applications where machine screw pitch threads are preferable to spaced thread tapping screws, or where chips

from thread cutting types are objectionable. Caution: In applications including long thread engagement or hard materials this type

screw may require extreme driving torque.

KAPTIV® Screws: The KAPTIV Screw combines a coarse pitch starting thread similar to a Type "B" Tapping Screw, with two or three pitches of coarse thread, followed by a finer pitch of thread approximating machine screw thread. The coarse threads are first formed in the engagement hole. With continued driving the coarse pitch threads in the hole are re-tapped with the finer pitch of thread. When the screw is backed out to the junction of the two pitches of thread, the coarse thread will not follow the path of the fine thread and, consequently, the screw will stop and will be captive. The KAPTIV Screw

is recommended In electrical terminal strips, keyhole cut-outs and other captive screw applications.

P-K TAPITS: This is a self-drilling screw similar in appearance to the

Type "A". P-K TAPITS have the capability of penetrating a total metal thickness of .050" without a predrilled or punched hole. A twin

lead thread provides fester entry. Serrations are under the head to prevent stripping.

TYPE ·u· Metallic Drive Screw: A multiple threaded screw with a steep

helix angle, and an entering pilot. This screw is designed for use in

metal end plastics, where a permanent fastening is desired.

1 76

TYPE '21 ": This fastener has a modified pan head. Type "U" thread configurations, annular rings under the head, and a cuneiform point.

This screw is intended for piercing light gages of metal, to fasten fabrics, leather, etc., to the metal. It is designed as a permanent fastening.

B. Thread Cutting Screws. For application in materials where disruptive internal stresses are not desirable, or where excessive driving torques are encountered with Thread Forming Screws, the following

types of Thread Cutting Screws may be used within the range of recommendations.

TYPE 'BF': The "BF" Screws have the spaced thread as on Type "B', a blunt point, and tapered entering threads. Additionally, there are five cutting flutes spaced equidistant on the entering taper, to cut e thread in the engagement material. "BF" Screws are particularly adaptable for cutting threads in hard friable plastic materials such as phenol, urea, acetates, and melamines.

TYPE "F": The Type "F" has machine screw type threads that approximate unified thread form, with a blunt point and tapered entering threads. There are five cutting flutes spaced equidistant on the entering taper. The Type "F" Screws performs well on all gages of metal, plastics, ferrous and non-ferrous castings, etc., it is adaptable in applications where removal and reinsertion is a prerequisite.

TYPE "L': The Type "L" Thread Cutting Screw is similar to the Type "B" Thread Forming Screws, but it is provided with a predetermined starting taper having a tapered flat on the starting point. For use in nylon and similar plastics. The Type "L" Thread Cutting Screw has

a combination function since it forms the initial thread and it also cuts away excess material that has been extruded by the forming threads.

C. Special Purpose Screws PANEL-KWICK® This special purpose fastener is used primarily to fas

ten drywall to metal lath. This fastener has a twin lead thread and sharp gimlet point. A patented left hand thread under the head prevents paper from being torn during the driving operation. The deep cross-hatching on the head surface provides a gripping base for all types of spackling.

PANEL-KWICK® II: The PANEL-KWICK II Screw combines the features of the PANEL-KWICK Screw with the drill point of DRI L-KWICK Screw. This versatile fastener is used where building codes specify a heavier lath to .060" thick.

STAPS®: A Type "A" or "B" Screw, with a hex head, assembled with a

cupped steel washer and a neoprene washer, or a special integral cupped washer hex head, assembled with a neoprene washer. It is

primarily used for fastening corrugated siding.

D. High-Performance Screws DRIL-KWICK® Screw: A high performance fastener that drills, taps and

fastens in a single operation, generally in five seconds or less. Standard DRIL-KWICK Screws are manufactured with the spaced "B" thread (BSD) and machine screw type thread (CSD) Both thread configurations are manufactured in phillips pan and hex washer head styles, as a standard. Both head styles have serrations under

the head, to prevent fastener strippage.

GENERAL DATA ON TAPPING SCREWS SWAGEFORM® Screw: A thread-forming high performance screw with a blunt point and having threads approximating those of machine screws. The tapered entering thread has lobes (or projections) spaced approximately 1 20 degrees apart in circumference. A lobe extends from the crest of the thread to the flanks and ends near the root of the screw. The SWAGEFORM Screw is primarily recommended for use In heavy gage metals, steel, brass, zinc, aluminum castings and forgings, etc., where the conventional thread-forming type of screw fails because of the high driving torque and low holding power.

SWAGEFORM® B: A thread forming high performance screw with blunt point, having threads similar to Type "B". The tapered entering thread has lobes apart in circumference. A lobe extends from the root of the screw. The SWAGEFORM B is intended primarily for plastics, zinc and aluminum die castings and heavy gage sheet meter.

2. REQUIREMENTS A. Head Bearing Surface, other than countersunk, shall be at a right

angle to the axis of the screw within 2°.

B. Eccentricity. Eccentricity is defined as one-half of the full or total indicator reading.

B.1 Eccentricity of Head. The heads of tapping screws shall not be eccentric with the axis of the screw bodies by more than 3% of the head diameter.

B.2 Eccentricity of Recess. The recess in recessed head tapping screws shall not be eccentric with the axis of the screw body by more than 6%; of the basic screw diameter or .01 5 in. whichever is greater.

B.3 Eccentricity of Slot. The slot in slotted head tapping screws shall not be eccentric with the axis of the screw body by more than 6%; of the basic screw diameter or .01 0 in. whichever is greater.

C. Head Height All dimensional head heights given in tables represent a metal to metal measurement.

D. Depth of Slots are measures from the top of the head to the intersection of the bottom of the slot, parallel to the axis of the screw.

E. Recess Depth is measured parallel to the axis of the screw from the rounded intersection of the head surface and the maximum diameter of the recess to the bottom of the recess.

F. Underhead Fillet is the radius which is located at the junction of the perpendicular bearing surface and the body of the screw and cannot exceed 1 5% of the major basic diameter. The countersink head fillet radius cannot exceed 40% of the basic major diameter.

G. Length of Screw shall be measured from the largest diameter of the head bearing surface to the extreme point in line parallel to axis of the screw.

H. Length Tolerances of Type 'A", "BP" and 'AB" .030" on lengths up to 1 " long inclusive, on longer lengths plus .050" and minus .050'. For Types "B", "BF', "C', "F" and SWAGEFORM® Screws, the tolerance in length shall be plus nothing and minus .030" on lengths up to 3/4", inclusive; plus nothing and minus .050" on lengths greater than 3/4"to 1-1/2", inclusive; plus nothing and minus .060" on lengths over 1 -1/2". For Type "U" Metallic Drive Screws, the tolerance in lengths shall be plus .020' and minus .020" on lengths from 1/8" to 3/8' 1ong, inclusive; plus .030" and minus .030' 1engths greater than 3/8".

I. Thread Length and Body Diameters Type "A", 'AB", "B", "BP", "BF" and "L". Screws up to eight diameters in length shall be threaded close to the head, so that the specified minor diameter limits are maintained within one pitch (thread) of the underside of the head. Lengths greater than eight diameters unless otherwise specified, shall be threaded at the discretion of the manufacturer but must be threaded at least six diameters. The diameter of the unthreaded section shall not be g reater than the maximum major diameter or less than the minimum minor diameter.

Types "C", "F" and SWAGEFORM Threads must extend to within one pitch (thread) otthe head on screw lengths up to and including three diameters. Up to and including eight diameter threads must extend up to within two pitches (threads) of the head.

On longer lengths, unless otherwise specified, the length of thread is at the discretion of the manufacturer but must be at least six diameters. The unthreaded body diameter shall not be greater than the maximum major diameter or less than the Class 2A minimum pitch diameter.

J. Entering Taper. The entering end of Type "B", "L" and "C" Thread Forming Screws are tapered to assist in entering and tapping the hole. Tapered threads may have unfinished crests. The Types "F" and "BF" Thread Cutting Screws including the taper shall have complete and sharp threads to assist the entering of the screw by cutting the material with a minimum amount of torque.

Types "B", "BF" and "L" Taper lengths shall be maximum 2-1/2 inches times the pitch of the thread. SWAGEFORM Screws shall have a taper, with lobes of two to three and one-half pitches.

K. Materials. Tapping Screws must be of high quality steel and must meetthe specified requirements. Drive Screws shall be made of steel, which can form mating threads in recommended hole sizes in steel test plates having a Rockwell hardness of B70-85 maximum or cast iron, without shearing threads or breaking screws.

Tapping or Drive Screws made from materials other than steel are not covered in performance specifications.

L. Hardness. Tapping Screws are case hardened and will meet the performance requirements of test specifications of Types "A", "AB", "B", "C" and "F" Screws.

M. Testing by means of the drive test. Tapping Screws must form a mating thread in the test plates by cutting or displacing material without deforming their own thread, until the tapered threads of the point extend through the entire thickness of the test material.

This test is based on plain finished screws, and if the plated screws fail this test, additional screws will be stripped of plating, baked and retested in plain finish, but lubricated with machine oil. Test plates shall be made from half hard low carbon cold rolled steel, with a Rockwell hardness of B70-85.

N. Torsional Strength Test. Follow the succeeding procedure:

( 1 ) A screw is clamped with at least two threads extending above the clamping device and at least two threads held in the clamping device, not using any of the threads on the taper.

(2) Torque is applied to the screw.

(3) This torque is measured by a calibrated gage and must equal or exceed the minimum torsional strength.

ISO Metric screw threads are designated by basic diameter and thread pitch. As an example, M 8 x 1 is a standard ISO Metric screw thread having a basic diameter of 8 mill imeters and a thread pitch of 1 millimeter. To convert an ISO

Metric screw thread designation to a Unified (American) designation divide the basic diameter by 25.4 and multiply the reciprocal of the pitch by 25.4 to determine nominal size in inches and threads per inch. By so doing, M 8 x 1 becomes 0.31 5-25.4 UNS.

Unified screw threads are designated by nominal size and number of threads per inch. As an example, 3/4 - 10 UNC is a standard Unified screw thread having a nominal size of 3/4 inches and 10 threads per inch. To convert a Unified screw thread designation to an

ISO Metric screw thread designation multiply nominal size by 25.4 and multiply the reciprocal of threads per inch by 25.4 to determine basic diameter in mill imeters and pitch in mill imeters. By so doing, 3/4 - 10 UNC converted to ISO Metric becomes M 1 9.05 x 2.54.
