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 code listed by ICC-ES under the 2012, 2015, 2018 and 2021 IBC and IRC.
- 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 
- SSTB is suitable for monolithic and two-pour concrete applications 
- Diameter: 5/8-in 
- Length: 17-5/8-in 
- Material: ASTM F-1554, Grade 36 
- Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications
