Product Description
Simpson SSTB34 Anchor Bolt 7/8 in. x 34-7/8 in. is an engineered anchor bolt purpose-built for maximum performance when securing holdowns and Simpson Strong-Tie Strong-Wall shearwalls to concrete foundations. Fabricated from ASTM F-1554, Grade 36 uncoated steel and made in the United States, this anchor bolt has undergone extensive testing to determine design load capacity across many common applications. The Simpson SSTB series is code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC, making it a trusted choice for residential and light commercial structural connections where code compliance is essential.
Key Features
- Identification on the bolt head showing embedment angle and model - lets installers quickly confirm correct bolt orientation and model on the job site, reducing placement errors before concrete is poured.
- Offset angle design - reduces side bursting forces in the surrounding concrete and provides greater concrete cover around the bolt, contributing to a stronger, more durable anchor installation.
- Rolled thread construction - delivers higher tensile capacity compared to cut threads, supporting the demanding load requirements of holdown and shearwall applications.
- Stamped embedment line on the bolt - serves as a clear visual guide during placement so the bolt is set to the correct depth every time, simplifying installation and improving consistency.
- Compatible with monolithic and two-pour concrete applications - gives builders and contractors flexibility across a wide range of foundation types and construction schedules without requiring a different product.
Why This Product
- Engineered specifically for holdowns and Strong-Wall shearwalls - unlike general-purpose anchor bolts, the SSTB34 is designed and extensively tested for the precise applications where shear and uplift loads are greatest, giving structural engineers and builders a bolt they can specify with confidence.
- ICC-ES code listed under multiple IBC and IRC editions - coverage under the 2012, 2015, 2018, and 2021 codes means this bolt meets inspection requirements across jurisdictions using different adopted code cycles, reducing approval uncertainty on permitted projects.
- Built-in installation aids minimize field errors - the stamped embedment line and head identification markings work together to guide correct depth and orientation before the pour, helping crews avoid costly mistakes without relying on separate templates or layout tools.
- Rolled thread and offset angle deliver structural confidence - the combination of higher tensile capacity from rolled threads and reduced side bursting from the offset angle means the SSTB34 is engineered to perform where foundation anchor bolt failure is not an option.

Frequently Asked Questions
What concrete pour methods is the SSTB34 compatible with?
The SSTB34 is suitable for both monolithic and two-pour concrete applications, providing flexibility for a variety of foundation and construction scenarios.
Are nuts and washers included with the SSTB34?
No. Nuts and washers for holdown attachment are not supplied with the SSTB; install standard nuts, couplers, and/or washers as required.
What building codes cover the SSTB34?
The Simpson Strong-Tie SSTB anchor bolts are code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC.
How does the offset angle design benefit installation?
The offset angle on the SSTB34 reduces side bursting forces in the concrete and provides greater concrete cover around the bolt, contributing to a stronger, more durable installation.
