Product Overview
SSTB28 Anchor Bolt
7/8IN DIA 29-7/8IN ANCHOR BOLT
The SSTB anchor bolt is designed for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie Strong-Wall shearwalls. Extensive testing has been done to determine the design load capacity of the SSTB when installed in many common applications.
The Simpson Strong-Tie SSTB anchor bolts are code listed by ICC-ES under the 2012, 2015, 2018 and 2021 IBC® and IRC®.
Key Features
- Identification on the bolt head showing embedment angle and model
- Offset angle reduces side bursting, and provides more concrete cover
- Rolled thread for higher tensile capacity
- Stamped embedment line aids installation
- Available in HDG for additional corrosion resistance
Material
- ASTM F-1554, Grade 36
Finish
- None. May be ordered HDG.
Installation
- SSTB is suitable for monolithic and two-pour concrete applications.
- Nuts and washers for holdown attachment are not supplied with the SSTB; install standard nuts, couplers and/or washers as required.
- On HDG SSTB anchors, chase the threads to use standard nuts or couplers or use overtapped products in accordance with ASTM A563, for example Simpson Strong-Tie NUT5/8-OST, NUT7/8-OST, CNW5/8-OST, CNW7/8-OST.
- Install SSTB before the concrete pour using AnchorMate® anchor bolt holders. Install the SSTB per the plan view detail.
- Minimum concrete compressive strength is 2,500 psi.
- When rebar is required it does not need to be tied to the SSTB.
- Order SSTBL models (example: SSTB16L) for longer thread length (16L = 5 1/2", 20L = 6 1/2", 24L = 6", 28L = 6 1/2"). SSTB and SSTBL load values are the same. SSTB34 and SSTB36 feature 4 1/2" and 6 1/2" of thread respectively and are not available in "L" versions.
GFCMU (Grout-Filled Concrete Masonry Units) - One horizontal #4 rebar in the second course.
- One vertical #4 rebar in adjacent cell for 5/8"-diameter SSTB.
- One vertical #4 rebar in an adjacent cell and additional vertical #4 rebar(s) at 24" o.c. max. for 7/8"-diameter SSTBs (2 total vertical rebars for end wall corner, 3 total vertical rebars for midwall).
For two-pour (4" slab) installation loads: - When using the SSTB20, use the equivalent loads of the SSTB16.
- When using the SSTB24, use the equivalent loads of the SSTB20.
- When using the SSTB34 or 36, use the equivalent loads of the SSTB28.
