Product Description
The Simpson SSTB28LHDG is a hot-dip galvanized anchor bolt engineered specifically for maximum performance in holdown and Simpson Strong-Wall shearwall applications. Backed by extensive testing across many common installation scenarios, this anchor bolt carries an ICC-ES code listing under the 2012, 2015, 2018, and 2021 IBC and IRC, giving builders and engineers a trusted, code-compliant foundation for demanding structural connections. Compatible with both monolithic and two-pour concrete applications, it delivers consistent, verified load capacity wherever secure sill plate and shearwall anchoring is required.
Key Features
- Bolt head identification showing embedment angle and model - lets installers quickly verify correct placement and orientation on the job site, reducing the risk of costly installation errors.
- Offset angle design - reduces side bursting forces and provides more concrete cover, improving structural integrity in the concrete pour.
- Rolled thread construction - produces higher tensile capacity than cut threads, so the bolt resists pull-out forces more effectively under load.
- Stamped embedment line on the bolt - gives a clear visual guide during concrete placement, helping ensure the bolt is set at the correct depth without guesswork.
- Compatible with both monolithic and two-pour concrete applications - gives contractors flexibility across a wide range of foundation and wall construction methods without needing a different fastener for each scenario.
- Hot-dip galvanized coating - delivers extra corrosion resistance for exterior environments and treated-wood applications where standard finishes would degrade over time, protecting the structural connection for the life of the structure.
- ASTM F-1554, Grade 36 material - meets a widely recognized steel standard, supporting confidence in the bolt's mechanical properties and compatibility with engineered holdown systems.
Why This Product
- Purpose-engineered for holdowns and Strong-Wall shearwalls - unlike generic anchor bolts, the SSTB was designed and extensively tested specifically for these high-demand structural connections, providing design load data builders can rely on.
- ICC-ES code listed for multiple code cycles - coverage under the 2012, 2015, 2018, and 2021 IBC and IRC means this anchor bolt fits projects across a broad range of jurisdictions and inspection requirements without substitution hassles.
- Built-in installation aids minimize field errors - the stamped embedment line and bolt head identification work together to guide correct placement, helping crews get the anchor set right the first time and avoiding costly remediation.
- Hot-dip galvanized finish extends service life in corrosive conditions - for exterior foundations and pressure-treated wood framing where moisture exposure is a long-term concern, the HDG coating provides a meaningful durability advantage over uncoated or lightly coated alternatives.

Frequently Asked Questions
What concrete pour methods are compatible with the SSTB28LHDG anchor bolt?
The SSTB28LHDG is suitable for both monolithic and two-pour concrete applications, making it versatile for a range of common construction scenarios. Extensive testing has been conducted to determine the design load capacity of the SSTB when installed in these applications.
Why is the hot-dip galvanized finish recommended for certain applications?
The hot-dip galvanized (HDG) coating offers extra corrosion resistance compared to standard finishes, making the SSTB28LHDG especially well suited for exterior applications and installations involving treated wood, where exposure to moisture or corrosive elements is a concern.
Are nuts and washers included with the SSTB28LHDG, and are there any special threading considerations?
Nuts and washers for holdown attachment are not supplied with the SSTB28LHDG. Additionally, on HDG SSTB anchors, the threads should be chased in order to use standard nuts or couplers.
What building codes cover the SSTB28LHDG, and what primary applications is it designed for?
The SSTB28LHDG is code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC. It is designed for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie Strong-Wall shearwalls.
