SSTB® Anchor Bolt

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 code listed by ICC-ES under the 2012 and 2015 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; 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, 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.

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.

  1. See notes to the Designer below.
  2. SSTB28, SSTB34 and SSTB36 with 3 7/8" end distance allowable loads are 6,605 lbs. (Wind and SDC A&B) and 5,550 lbs (SDC C-F).

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 SB bolts are as shown in graphics.
  3. To obtain LRFD values for cast-in-place anchor bolts, multiply ASD seismic load values by 1.4 and wind load values by 1.6 (1.67 for 2015 IBC).
  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.
  5. Allowable loads are based on the average ultimate load with a safety factor of 5.0 per ACI 530.
