Product Description
The Simpson SSTB 5/8 in. x 28 1/8 in. Hot-Dip Galvanized 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 installation scenarios, this anchor bolt is code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC - giving contractors and engineers the confidence of verified, tested performance. The hot-dip galvanized finish delivers extra corrosion resistance, making the SSTB24LHDG an especially reliable choice for exterior and treated-wood applications where long-term durability is a priority.
Key Features
- Identification on the bolt head showing embedment angle and model - makes it easy to verify correct installation in the field, reducing the risk of costly errors.
- Offset angle - reduces side bursting and provides more concrete cover, helping protect structural integrity within the concrete foundation.
- Rolled thread - delivers higher tensile capacity compared to cut thread, so the bolt can handle the demanding loads common in holdown and shearwall applications.
- Stamped embedment line - aids installation by giving installers a clear, built-in reference mark, taking the guesswork out of proper placement depth.
- Compatible with both monolithic and two-pour concrete applications - provides flexibility to work across a wide range of common foundation and construction scenarios.
- Hot-dip galvanized coating - offers extra corrosion resistance for exterior and treated-wood applications where standard finishes may not hold up over time.
Why This Product
- Engineered specifically for holdown and shearwall use - unlike general-purpose anchor bolts, the SSTB is purpose-built and extensively tested for holdown attachment and Strong-Wall shearwall installations, so you get design load data you can actually rely on.
- Code-listed confidence across multiple code cycles - ICC-ES listing under the 2012, 2015, 2018, and 2021 IBC and IRC means this anchor bolt meets the requirements inspectors and engineers expect, helping projects move forward without compliance concerns.
- Built-in installation aids reduce field errors - the stamped embedment line and bolt-head identification markings work together to help crews install the bolt correctly the first time, saving time and avoiding costly rework.
- HDG finish extends service life in demanding environments - the hot-dip galvanization provides a durable corrosion barrier that makes this anchor bolt a dependable long-term choice for exterior conditions and treated-lumber applications where moisture and chemical exposure are ongoing concerns.

Frequently Asked Questions
What is the hot-dip galvanized finish used for on the SSTB24LHDG?
The hot-dip galvanization (HDG) finish offers extra corrosion resistance, making the SSTB24LHDG particularly suitable for exterior applications and treated-wood applications where standard finishes may not provide adequate protection.
Are nuts and washers included with the SSTB24LHDG?
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.
What concrete application types is the SSTB24LHDG compatible with?
The SSTB anchor bolt is suitable for both monolithic and two-pour concrete applications, providing flexibility across a range of common installation scenarios.
What building codes cover the SSTB24LHDG anchor bolt?
The Simpson Strong-Tie SSTB anchor bolts are code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC, ensuring broad code compliance for residential and commercial construction projects.
