KC Metal Anchor Downs, Anchor Bolts, Anchors, FoundationAngles and Foundation Straps.
2.0 DESCRIPTION
2.1 AD, AD-A and AD-B Anchor Down Series:
The Anchor Down anchors connect vertical wood members toconcrete foundations having a minimum compressivestrength of 2,500 psi (17.2 MPa) at 28 days. The anchorconsists of a steel plate that is fabricated into a taperedchannel section, and a horizontal steel plate seat welded tothe channel web. The steel complies with ASTM A 570 Grade33 requirements. The channel web and plate seat haveprepunched bolt holes for bolt connections to the face of thestud or post and to the foundation.
The AD series Anchor Downs must be placed, from the topof the mudsill or plate to the first bolt closest to the plate seat,a minimum of 43/8 inches (111 mm) for AD2; 51/4 inches (133mm) for AD5 and AD6; 61/8 inches (156 mm) for AD7; and 7inches (178 mm) for AD9, AD12 and AD15.
The AD-A and AD-B series Anchor Downs are designed toprovide sufficient distance between prepunched bolt holes tomeet the required seven-bolt-diameter minimum end distancefor the first bolt closest to the plate seat. The die-formedanchor bent channel is welded to the web above the first bolthole. The AD-A series Anchor Downs have a 3/16-inch- (4.7mm) to 3/8-inch-thick (9.5 mm) ASTM A 36 steel load transferplate, tack-welded to the seat. See Figure 1 for descriptivedetails. Table 1 specifies fastener schedules, minimumembedment of anchor bolts and allowable loads.
2.2 KCAB Super Speed Anchor Bolt Series:
The anchor bolts resist uplift forces imposed on vertical woodmembers and foundation attached to any uplift-resistingconnector. The anchor bolts are manufactured from steelcomplying with ASTM A 307. The bolts have threads at oneend and a loop and reverse hook at the other end. The
minimum compressive strength of normal-weight concrete is2,500 psi (17.2 MPa) at 28 days. Dimensional characteristicsand allowable loads are set forth in Table 2. See Figure 2 fordescriptive and installation details.
2.3 SA, SAI, SAM, SAT, SAMT, HSA and HSAT StrapAnchor Series:
These strap anchors provide wind and seismic anchorage forconcrete walls anchored to wood floor or roof diaphragms.The strap anchors are made from No. 12 gage or No. 10 gageby 2-inch-wide (51 mm) galvanized steel. The embossed end,which has a right-angled bend and a 2-inch (51 mm)extension, is embedded 4 inches (102 mm) into minimum2,000 psi (1.4 MPa) concrete, with the strap anchor lying overthe top of the wall ledger or blocking.
The HSA series anchors are similar to SA anchors, andhave embedment depths of 6 inches (152 mm) for the HSA28and 81/4 inches (210 mm) for the HSA35. HSAT anchors areidentical to the HSA except for a 90-degree twist in the strapto facilitate attachment to the side of a purlin.
The SA51 and SA68 strap anchors are designed to provideuplift resistance to double 2x band joist and raised floorfoundation systems subjected to wind or earthquake loading.The strap anchors are fabricated from ASTM A 653 SS Grade37 steel. The SA2545, SA3522, HSA3522 and HSA3522-2Pare for installation in concrete footings where horizontal coldjoints exist between the slab and the footing or foundationwall. The anchor is installed with a minimum No. 4 reinforcingbar installed in and parallel to the concrete footing, in theshear cone, having a minimum length of 24 inches (610 mm),centered at the anchor. Minimum anchor embedment depthsinto concrete for the HSA3522, HSA3522-2P, SA2545 andSA3522 are 10 inches (254 mm), 14 inches (356 mm), 6inches (152 mm) and 8 inches (203 mm), respectively. SeeFigure 3 for descriptive details. Table 3 specifies strapdimensions, fastener schedules and allowable loads.
2.4 WA, WAL, WAM, WAH and WAI Wall Anchor Series:
These anchors are similar to HSA wall anchors except thatthe bent ends are not embedded in concrete. WA, WAL andWAI anchors have a bent 90-degree seat, and WAM andWAH anchors have a die-formed seat, attached to straps ofvarious lengths with prepunched nail and bolt holes. Theanchor bolt type and embedment in the concrete wall requireanalysis and design. Table 4 specifies anchor dimensions,fastener schedules and allowable loads. The No. 18 and No.16 gage steel used to fabricate the anchors conforms toASTM A 653 SS Grade 33 steel, and the No. 12 and No. 11gage steels conform to ASTM A 653 SS Grade 37 steel. SeeFigure 4 for descriptive details and typical installation.

2.5 SSAD Super Speed Anchor Down Series:
SSAD strap anchors are die-formed from No. 12 gage by 3-inch-wide (76 mm) galvanized steel meeting the requirementsfor ASTM A 653 SS Grade 40 steel. These strap anchors aresimilar to HSA3522 strap anchors, and are for installation inconcrete footings or foundation walls. The anchor is hookedaround a minimum No. 4 by 24-inch-long (610 mm)reinforcing bar and provides uplift resistance to double 2-byor solid wood posts undergoing wind or seismic loading. Thestrap has embossed markings for nails installed with a nailgun. Table 5 specifies stem wall thickness, minimumembedment into concrete, fastener schedules and allowableloads. See Figure 5 for descriptive and installation details.
2.6 RFA Retrofit Foundation Angles Series:
These angles are die-formed from No. 12 gage galvanizedsteel meeting the requirements for ASTM A 653 SS Grade 37steel. The top horizontal legs of the angles have prepunchednail and bolt holes for attachment to the mudsill plate, andvertical legs of the angles have two bolt holes for attachmentto the concrete foundation. These angles are used forattaching existing sill plates to existing concrete stem walls.The angles have slots at the bend line which allow foradjustment of the angle for attachment to sloping stem walls.Table 6 specifies dimensions, fastener schedules andallowable loads. See Figure 6 for descriptive details andtypical installation.
2.7 RFS Retrofit Foundation Strap Series:
These straps are die-formed from No. 12 gage galvanizedsteel meeting the requirements for ASTM A 653 SS Grade 37steel. The straps are designed for the retrofitting of existingstructures. Straps attach existing stud or joist to foundationstem wall. Straps may be attached to stud or joist with nailsor bolts, and to the existing foundation stem wall with retrofitanchor bolts. Table 7 specifies strap dimensions, fastenerschedules and allowable loads. See Figure 7 for descriptiveand installation details.
2.8 Design:
Allowable loads for the connectors described in this report arefor connectors installed on wood members having a minimumspecific gravity of 0.50, seasoned to a moisture content of 19percent or less used under continuously dry conditions. Forconnections in wood that is unseasoned or partiallyseasoned, or when connections are exposed to wet-serviceconditions, or where the in-service temperature exceeds100°F (37.8°C), the allowable loads in this report must bemultiplied by the adjustment factors specified in the NDS,1991 revised edition, as referenced in Chapter 23, Division III,of the 1997 Uniform Building Code™ (UBC). The maximumadjusted load shall not exceed the maximum design loadshown in the tables.
In designing wood members connected to the AD, AD-Aand AD-B series anchor downs, the following must beconsidered for single-shear applications:
• The wood member must be checked for its design capacityat the critical net section, reducing the gross sectionproperties for holes or other removed wood, for combinedbending and axial tension, due to eccentricity, and fortensile stresses in accordance with Section 3.9 of theapplicable NDS.
• The wood members must be checked for its designcapacity for compression parallel and perpendicular tograin.
• Allowable stresses and other adjustment factors, asapplicable, from the NDS must be used for checking the
design capacity of the wood member. Design capacities ofthe wood member may also be adjusted by a load durationfactor (CD) as specified in the UBC.
2.9 Installation:
KCAB bolts are to be installed prior to the pouring ofconcrete. Bolts are placed 45 degrees diagonally from thefoundation stem wall, in the direction of an indicator stampedon the bolt head. Bolts are placed in concrete complying withChapter 19 of the UBC. The bolts must have a minimum 13/4-inch (44 mm) edge distance and a minimum 5-inch (127 mm)end distance. See Figure 3 for details.
