Ensat is a self-tapping threaded insert with external and internalthreads, cutting slots or cutting bores. A continuous process of further development has brought about a num-ber of major improvements to productcharacteristics. These inserts areprotected by German and also foreignpatents.

Ensat®-S 302(with cutting slot) is recommended formost application cases. In certain mate-rials, this Ensat demonstates a minimalinward springing action, so creating acertain screw locking effect. If this effectis not required, we recommend usingEnsat-SB 307/308.

Ensat®-SB 307/308(with cutting bores) was developed formaterials with difficult cutting proper-ties. This insert has a thick wall and thecutting force is distributed over threecutting edges. The short version Ensat 307 is particu-larly suitable where minimal materialthicknesses are involved.

Thin-walled Ensat®-SD/SBDfor applications involving special spaceconditions (residual wall thicknesses),and also suitable for driving using athread tapping machine (same internaland external thread pitch). Slot version: Works Standard 303 Three-hole version: Works Standard 347/348(see page 9).

Ensat®-SBS 337/338with three chip reservoirs. Used primarily wherever only a small amountof chips may be permitted to occur du-ring the tapping process (see page 8).

Ensat®-SBTwith closed floor for additional sealing from below. Works Standard357/358. Dimensions: see Works Stan-dard 337/338 (see page 8).

Ensat®-3F 305 is a thread forming in-sert with 3 longitudinal grooves aroundist periphery.

Fields of application

The Ensat is used throughout the entiremetal and plastics processing industry.

Automotive industry, passengerand commercial vehiclesEngines, transmissions, wide range ofsupply parts such as side view mirrors,radiators, bumpers etc.

Plant and equipment constructionFlange joints, construction equipment,oil burners etc.

Household appliance and officemachinery productionVacuum cleaners, cameras, sun lamps,drills etc.

Electrical and laboratory suppliesCapacitors, heavy current, radio andtelecommunication systems, dentaltechnology equipment.

Military applicationsTanks, aircraft etc.

Ensat®-SBS 337/338These cutting bores are shaped to serveas chip reservoirs. The chips created du-ring the diving process are stored hereand cannot drop into sensitive equip-ment parts. For additional sealing from

below: Ensat with closed floor: WorksStandard 357/358 Dimensions: SeeWorks Standard 307/308 (see page 7).

Product features

• The Ensat has a large effective she-aring surface (E B), so ensuring ahigher degree of pull-out strength,i.e. an Ensat M4 is often sufficientinstead of a cut M5 thread.

• The Ensat is driven subsequently intothe finished workpiece. This means ahigher casting machine output, norejects due to incorrectly cast-in in-sert components, no molding sandtrapped in the thread.

• A pre-cast or pre-drilled retaininghole with normal tolerance require-ments is sufficient for driving in theEnsat. The thread is always preciselypositioned.

• The work steps required with wireinserts – thread tapping, breakingoff trunnions etc. as well as costlywearing tools (special thread drills,limit plug gauges etc.) are notrequired with the Ensat-system.

• The Ensat is insensitive to smallareas of shrinkage. The Ensat-systemprevents damage caused by tornthreads.

• Universal application for all types ofplastic, thermoset plastics, thermo-plastics, PU/PUR foam, fiberglassreinforced plastics, for hardwood andplywood, particle board and metal.

• Maximum strength values in compa-rison to other systems. The diagramillustrates the withdrawing force inthermoplastic materials: In thermosetplastics and glass fiber reinforcedplastics, the values tend to be higher.

Borehole diameter:Brittle, tough and hard materials call fora larger borehole than soft or elasticmaterials. For guideline values, see thetable above.

Edge distance:The smallest still admissible edgedistance depends on the planned stresslevel and the elasticity of the materialinto which the Ensat is installed.

Sinking the receiving holeFor a clean fit of the Ensat flush withthe surface, the following injection orpressed hole form is recommended:Chamfer soft to medium-hard plasticsto 60°. For hard and brittle plastics: Pre-inject or pre-press with N = E + 0.008to 0.016. Sinking depth X ≥ pitch of theEnsat male thread.

In molded parts made of glass fiberreinforced plastic, a high pull-out resis-tance is reached if the casting skin isremoved in the receiving hole by drillingopen.

Avoid any tilting between the Ensat andthe screw – under the head or in thethread. For this reason, in the case ofadjusting screws the Ensat is driven into a depth of ≥ 0.004. Studs must befixed against the floor surface of theblind hole.

Example:

Female thread 5/16-18, recommendedBorehole diameter for:

Light alloy workpiece (Rm=280N/mm²), Ensat®-S 302: 0.441 to 0.449Ensat®-SB 307/308: 0.441 to 0.445

Plastic workpieceEnsat®-S 302: 0.429 to 0.441Ensat®-SB 307/308: 0.437 to 0.445

In case of processing problems (e.g.extreme screw-in torque levels), it isgenerally of no consequence to choosea higher bore diameter. In case ofdoubt, it is worth testing this. For moreinformation also please see technicalpublication 20 inserts for metal; ortechnical publication 30 inserts forplastic and wood.

Installation recommendation

The Ensat should be processed approx.0.004 – 0.008 recessed. After pro -cessing, the Ensat can be immediatelysubjected to load. If the componentmaterial permits subsidence of theEnsat under load, the Ensat can onlyexecute an axial movement of 0.004 to0.008. In other words, the pretension ofthe screw union is largely retained,loosening of the screw connectionunder dynamic load is impeded.

Retaining hole

The retaining hole can be simply drilledor already provided for in the casting.

It is generally not necessary to counter-sink the hole. However, we do recom-mend that you take care not to warpthe workpiece surface when screwing inthe Ensat.

Material thickness:Length of the Ensat = smallest admissible material thickness M.

Depth of the blind hole:Minimum depth -T see Works Standardsheets, page 6 to 13.

Guidline values for light alloys:W ≥ 0.004 to 0.024 E

Guidline values for cast iron:W ≥ 0.012 to 0.02 E

Machine Ensat® installation …

Manual Ensat®installation …

Machine driving process

1. Precisely position the workpiece toensure that the hole and machinespindle are in exact alignment (donot tilt). Set the machine to the pre-cise driving depth (approx. 0.004 –0.008 below the surface of theworkpiece).

2. Turn the machine to clockwise rota-tion. At the start of the driving pro-cess, the rotatable external shell ofthe tool must be resting against theexternal visible stop pins in such away that it is driven by the pins inthe clockwise direction.

3. Feed the Ensat towards the tool(slot or cutting bores facingdownwards) and grip for the duration of 2 to 4 revolutions.

4. Actuate the operation lever of themachine until the Ensat cuts intothe borehole. The remainder of thedriving process takes place withoutactuating the feed.

5. Switch on the reversing function.Always avoid setting the tool downhard on the workpiece, as this can

lead to breaking both the tool andthe Ensat.

Excessively hard contact of the toolcan damage the play-free fit of theEnsat and so reduce the pull-outstrength. If necessary, the drivingspeed may have to be adapted inline with the necessary reversal time.

Machine installation takes place withproduction tool 620 or 621, integratedin a:

1. Thread tapping machine

2. Use a drill press fitted with a reversing tapping attachment or atapping machine which is not pitchcontrolled. Important: Never exceedthe maximum admissible driving torque.

3. Special manual machine with bitstop and reversing system.

4. For large-scale series:Single or multiple installation machines with pneumatic or electricdrive, semi or fully automatic, CNC.

For medium-hard light alloys:Cutting oil, spirit or petroleum.

Manual installation

Manual driving takes place using thedriving tools 620, 621 or 610 and a tapwrench:

1. Drill the hole according to the technical publication for the correctdiameter, countersink if necessary.

2. Screw the Ensat onto the drivingtool with the cutting slot or cuttingbore pointing downwards.

3. Drive in the Ensat until approx.0.004 – 0.008 below the surface ofthe workpiece. Ensure that it doesnot tilt! When using tool 620 and621, the rotatable shell must restagainst the externally visible stoppins in such a way that it is drivenround clockwise by the pins.

4. Back out the driver tool. During thisprocess, tool 620 or 621 is automa-tically released from the Ensat. Tool610: Hold the hex nut using a span-ner until the lock breaks.

The correct length of the stud for theEnsat with cutting slot/ cutting bore results from the pitch of the outsidethread (see also illustration below;P=pitch of the outside thread).

• When assembling, tighten bothscrews (5) evenly.

• Insert the ball bearing (6).

• Push on the shell (2) until the ballstop locks into place. To ensure thatthe tool functions perfectly, it must

be possible to easily totate the shell.For short Ensats, grind down tool610 accordingly.

• If you wish the Ensat to be drivendeeper than 0.004 below the workpiece surface, screw off theguide bush (3) at the front.

Diameter: 0.004 to 0.008 smallerthan the Ensat receiving hole.

For mounting the thin-walled Ensat(Page 11), modified guide bushingsshould be used. (available on request)

Set or exchange the stud

• Pull off the shell (2) downwards offthe shaft (1).

• Release the locking screw (5).

• Screw the stud (7) in or out. Yellowcolor marking indicates the flattenedsurfaces for the locking screws.

Installation

The receiving hole is punched or drilled,but not deburred or countersunk.

With punched holes, Clifa is pressed infrom the punching burr side. The press-in process takes place on a plane parallel basis using a customary presswith adjustable pressure level, until thesurface of the shoulder in the Clifapress-in nut comes to rest flat againstthe surface of the sheet metal.

In the case of the Clifa-SP stud, thehead must be fully pressed in and cometo rest flush with the surface of thesheet metal.

Pressure which is too high or appliedonly on one side as well as inclinedsupport surfaces must be avoided wherever possible.

Press-in pressure as a guidline value for selection of the press

The optimum press-in pressure must be determined by trial and error.In the case of light alloys, depending on the alloy composition andsurface properties, higher press-in pressure levels may be necessary.Maximum retention is achieved when adhering precisely to therecommended hole diameter and tolerances.
