SSTB® Anchor Bolts

SSTB®

Bolts

This product's information may differ depending on the category of use. You are currently viewing details related to Bolts. You can also view product information related to the category: Wood Strong-Wall® Bolts

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 now code listed by ICC-ES under the 2009 and 2012 IBC® and IRC® to meet the requirements of ICC-ES acceptance criteria AC 399. ICC-ES ESR-2611 is the industry's first code report issued for proprietary anchor bolts evaluated to the criteria of AC 399.

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; contact Simpson Strong-Tie.

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 or NUT7/8-OST, CNW5/8-OST, CNW7/8-OST.
  • Install SSTB before the concrete pour using AnchorMates®. Install the SSTB per the plan view detail.
  • Minimum concrete compressive strength is 2500 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.
  • View step-by-step installation instructions in the Installer's Pocket Guide (S-C-INSTALL).

CMU

  • 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.

Notes to the Designer:
  1. Rebar is required at top of stemwall foundations but is not required for Slab-on-Grade Edge and Garage Curb, or Stemwall Garage Front installations.
  2. Minimum end distances for SSTB bolts are as shown in graphics.
  3. Multiply the tabulated ASD wind or seismic loads by 1.6 or 1.4, respectively, to obtain LRFD capacities.
  4. Per Section 1613 of the IBC, detached one- and two-story dwellings in SDC C may use "Wind and SDC A&B" allowable loads.
  5. See ESR-2611 for additional information.
  6. Midwall loads apply when anchor is 1.5 le or greater from the end. For bolts acting in tension simultaneously, the minimum bolt center-to-center spacing is 3 le.

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

  1. Loads are based on a minimum CMU compressive strength, f'm, of 1500 psi.
  2. Minimum end distance required to achieve midwall table loads is 1.5 le.
  3. Minimum end distance for corner/end wall loads is 4 1/4".
  4. Loads may not be increased for duration of load.
