NEW! SSTB14 is a diameter anchor bolt designed and tested specifically for shallow foundation installations. Extensive SSTB testing has been done to determine the design load capacity at a common application, the garage stem wall. Design loads are based on a series of five tests, with a three-times reduction factor. SPECIAL FEATURES: Rolled threads for higher tensile capacity. Offset angle reduces side-bursting, provides more concrete cover. Stamped embedment line aids installation. Configuration results in minimum rebar interference. MATERIAL: ASTM A36 FINISH: None. May be ordered HDG; check factory INSTALLATION: SSTB is used for monolithic and two-pour installations. Nuts and washers are not supplied with the SSTB; install standard nuts, couplers and/or washers as required. REINFORCED CONCRETE FOUNDATION Install SSTB before the concrete pour using AnchorMates (see page 22). Install the SSTB per plan view detail shown on page 34. Install one #4 rebar 3" to 5" (may be foundation rebar not post-tension cable) from the top of the foundation. The SSTB does not need to be tied to the rebar. Minimum concrete compression strength is 2500 psi. Unless noted otherwise, no special inspection is required for foundation concrete when the structural design is based on concrete no greater than 2500 psi (UBC Section 1701.5.1 and IBC Section 1704.4). Unless otherwise noted, do NOT install where: (a) a horizontal cold joint exists within the embedment depth between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load, or the slab is designed to resist the load imposed by the anchor; or (b) slabs are poured over concrete block foundation walls. REINFORCED CONCRETE BLOCK Before concrete pour, install diagonally at approx. 45 in the cell per plan view detail shown on page 34. Horizontal #4 rebar (minimum 56" long centered about the anchor bolt) approximately one rebar 12" from the top and two rebars approximately 28" from the top. Vertical #4 rebar (minimum 24" long) install with maximum 24" o.c. spacing. Grout all cells with minimum 2000 psi concrete. Vibrate the grout per the 1997 Uniform Building Code, Section 2104.6.2, 2003 International Building Code, Section 2104.1. CODES: See page 12 for Code Listing Key Chart.

Loads may not be increased for short-term loading. Loads apply to earthquake and wind loading. 2. Minimum anchor center-to-center spacing is 2le for anchors acting in tension at the same time for full load. 3. The SSTB was tested in a stem wall with a minimum amount of concrete cover. 4. Maximum allowable load is 8150 lbs. for SSTB28, 34 and 36 when used 5" from the end of a concrete foundation. Use full table load when installed 24" from the end or installed in a corner condition (see illustration). 5. Connection is limited by the lowest of bolt or holdown capacity. 6. PHD and HTT minimum end distance is 4 ". 7. Order the SSTBL models for longer thread length (5 ex. SSTB24L. SSTBL and SSTB loads are the same. Not available on SSTB14. 8. SSTB34 has 4 of thread and SSTB36 has 6 ". These two models are not available in SSTBL versions. 9. Use 90% of the table load for 2000 psi concrete. 10. See page 34 for Additional Anchor Design information. 11. Allowable load for SSTB14 is 5020 lbs. when f' c = 3000 psi. See T-SSTB for additional information. 12. Minimum end distance required to achieve table loads is le.
