Product Description
The Simpson SSTB16LHDG SSTB 5/8 in. x 19-5/8 in. Hot-Dip Galvanized Anchor Bolt from Simpson is engineered for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie Strong-Wall shearwalls. Backed by extensive testing across common installation scenarios and code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC, this anchor bolt delivers the verified load capacity and code compliance that structural applications demand. Its hot-dip galvanized finish makes it a dependable choice for exterior and treated-wood installations where corrosion resistance is critical.
Key Features
- Identification on the bolt head showing embedment angle and model - lets installers quickly confirm the correct bolt and orientation on the job site, reducing costly errors.
- Offset angle design - reduces side bursting forces and provides more concrete cover, improving the structural integrity of the surrounding concrete.
- Rolled thread construction - delivers higher tensile capacity compared to cut threads, giving the connection greater resistance to pull-out forces.
- Stamped embedment line - provides a clear visual reference during placement so the bolt is set to the correct depth every time, simplifying installation.
- Compatible with monolithic and two-pour concrete applications - offers flexibility across different concrete pour schedules and construction sequences without requiring a separate product.
- Hot-dip galvanized finish - provides extra corrosion resistance suited for exterior environments and treated-wood framing where standard coatings may fall short.
Why This Product
- Purpose-built for holdowns and Strong-Wall shearwalls - the SSTB anchor bolt is specifically designed and extensively tested for these high-demand connections, so buyers get a solution with published load values rather than a generic fastener.
- Multi-code listed for broad project eligibility - ICC-ES code listing under the 2012, 2015, 2018, and 2021 IBC and IRC means this anchor bolt meets the requirements of inspectors and engineers across a wide range of current and recent building codes.
- HDG finish extends service life in demanding conditions - hot-dip galvanization provides a level of corrosion protection appropriate for exterior structural connections and applications involving treated wood, where moisture and chemical exposure are ongoing concerns.
- Installer-friendly details reduce guesswork on the job site - the combination of a stamped embedment line, bolt-head identification, and an offset angle geometry work together to make correct placement faster and more reliable, lowering the risk of installation mistakes.

Frequently Asked Questions
Are nuts and washers included with the SSTB16LHDG?
No. Nuts and washers for holdown attachment are not supplied with the SSTB. On HDG SSTB anchors, chase the threads to use standard nuts or couplers.
Is this anchor bolt suitable for two-pour concrete applications?
Yes. The SSTB is suitable for both monolithic and two-pour concrete applications.
Why does the SSTB16LHDG feature a hot-dip galvanized finish?
Hot-dip galvanization (HDG) offers extra corrosion resistance, making this anchor bolt appropriate for exterior and treated-wood applications where standard finishes may not provide adequate protection.
What building codes is the SSTB16LHDG listed under?
The Simpson Strong-Tie SSTB anchor bolts are code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC.
