Product Description
Simpson SSTB24L SSTB 5/8 in. x 28-1/8 in. Anchor Bolt is engineered by Simpson for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie Strong-Wall shearwalls. Backed by extensive testing to determine design load capacity across many common applications, this anchor bolt is code listed by ICC-ES under the 2012, 2015, 2018 and 2021 IBC and IRC - making it a reliable, tested solution for both monolithic and two-pour concrete construction.
Key Features
- Identification on the bolt head showing embedment angle and model - lets installers quickly verify the correct part and orientation on the job site, reducing costly errors.
- Offset angle reduces side bursting and provides more concrete cover - protects the surrounding concrete during and after installation, contributing to a stronger, longer-lasting connection.
- Rolled thread for higher tensile capacity - delivers greater pull-out resistance compared to cut threads, supporting the demanding load requirements of holdown and shearwall applications.
- Stamped embedment line aids installation - gives a clear, built-in reference mark so the bolt is set to the correct depth the first time, speeding up the pour process.
- Suitable for monolithic and two-pour concrete applications - offers flexibility across different foundation and slab construction methods without requiring a separate product for each scenario.
- Code listed by ICC-ES under the 2012, 2015, 2018 and 2021 IBC and IRC - simplifies plan approval and inspection sign-off by providing recognized third-party compliance documentation.
Why This Product
- Purpose-built for holdowns and Strong-Wall shearwalls - the SSTB anchor bolt is specifically designed and extensively tested for these critical lateral-force-resisting connections, giving structural builders and contractors a high-confidence, application-matched fastener.
- Structural design backed by testing, not guesswork - load capacity values are established through rigorous testing across common installation conditions, so engineers and inspectors can rely on published data when specifying this anchor bolt in lateral load applications.
- Engineered details that make installation faster and more accurate - the stamped embedment line, offset angle, and head identification work together to reduce layout time, minimize placement errors, and help crews set bolts correctly before the concrete is poured.
- Multi-code compliance across major code cycles - ICC-ES listing under four consecutive IBC and IRC editions means this bolt meets current adopted building codes in most jurisdictions, reducing the need to research substitutions or equivalencies for new construction projects.
