The SSTB anchor bolt is designed for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie®Strong-Wall® shearwalls. Extensive testing has been done to determine the design load capacity of the SSTB when installed in many common applications.

The Simpson Strong-Tie® SSTB anchor bolts are now code listed by ICC-ES under the 2009 and 2012 IBC® and IRC® to meet the requirements of ICC-ES acceptance criteria AC 399.. ICC-ES ESR-2611 is the industry’s first code report issued for proprietary anchor bolts evaluated to the criteria of AC 399. 

Special Features:

  • Identification on the bolt head showing embedment angle and model
  • Offset angle reduces side bursting, and provides more concrete cover
  • Rolled thread for higher tensile capacity
  • Stamped embedment line aids installation
  • Available in HDG for additional corrosion resistance

Material: ASTM F-1554, Grade 36

Finish: None. May be ordered HDGContact Simpson Strong-Tie.


    • SSTB is suitable for monolithic and two-pour concrete applications.
    • Nuts and washers for holdown attachment are not supplied with the SSTB; install standard nuts, couplers and/or washers as required.
    • On HDG SSTB anchors, chase the threads to use standard nuts or couplers or use overtapped products in accordance with ASTM A563, for example Simpson Strong-Tie® NUT5/8-OST or NUT7/8-OST.
    • Install SSTB before the concrete pour using AnchorMates®. Install the SSTB per the plan view detail.
    • Minimum concrete compressive strength is 2500 psi.
    • When rebar is required it does not need to be tied to the SSTB.
    • Order SSTBL Models (example: SSTB16L) for longer thread length (16L= 5 1/2", 20L = 6 1/2", 24L = 6", 28L = 6 1/2"). SSTB and SSTBL load values are the same. SSTB34 and SSTB36 feature 4 1/2" and 6 1/2" of thread respectively and are not available in "L" versions.

  • One horizontal #4 rebar in the second course.
  • One vertical #4 rebar in adjacent cell for 5/8" diameter SSTB.
  • One vertical #4 rebar in an adjacent cell and additional vertical #4 rebar(s) at 24" o.c. max. for 7/8" diameter SSTBs (2 total vertical rebars for end wall corner, 3 total vertical rebars for midwall)
