Product Description
The Simpson SSTB16L SSTB 5/8 in. x 19 5/8 in. Anchor Bolt is a Simpson engineered anchor bolt built for maximum performance in holdown and Strong-Wall shearwall applications. Designed to meet the demands of structural concrete connections, this anchor bolt has undergone extensive testing to determine design load capacity across many common installation scenarios. It is code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC, giving contractors and builders confidence in code compliance for both residential and commercial projects.
Key Features
- Bolt head identification showing embedment angle and model - lets installers quickly confirm correct orientation and placement in the field, reducing costly errors.
- Offset angle design - reduces side bursting forces and provides more concrete cover, protecting the surrounding material and improving long-term structural integrity.
- Rolled thread construction - delivers higher tensile capacity compared to cut threads, supporting greater load demands at the connection point.
- Stamped embedment line on the bolt - serves as a clear visual guide during installation, helping ensure proper embedment depth without guesswork.
- Compatible with monolithic and two-pour concrete applications - offers flexibility across a wider range of foundation and wall construction methods, making this bolt suitable for varied jobsite conditions.
Why This Product
- Purpose-engineered for holdown and shearwall use - the SSTB16L is specifically designed and tested for holdown connections and Simpson Strong-Wall shearwall applications, so you are not adapting a generic fastener to a critical structural role.
- Backed by ICC-ES code listings across four code cycles - compliance under the 2012, 2015, 2018, and 2021 IBC and IRC means this anchor bolt is recognized in current and recent building code environments, simplifying inspections and plan approvals.
- Performance data from extensive testing - published design load capacities derived from real-world application testing give engineers and contractors a reliable basis for specifying and installing this anchor bolt with confidence.
- Installer-friendly features built into the bolt itself - the stamped embedment line and bolt head identification work together to reduce installation mistakes, saving time and minimizing rework on the job.
