The SSTB is designed for maximum performance as an anchor bolt for holdowns and Strong-Wall® shearwalls. Extensive SSTB testing has been done to determine the design load capacity at a common application, the garage stem wall. Design loads are based on recent testing by Simspon Strong-Tie to the new ICC-ES acceptance criteria for cast-in-place proprietary bolts in concrete for light-frame construction (AC 399).

Special Features:

• Rolled threads for higher tensile capacity.
• Offset angle reduces side-bursting, provides more concrete cover.
• Stamped embedment line aids installation.
• Configuration results in minimum rebar interference.

Material:ASTM F1554 Grade 36

Finish: None. May be ordered hot-dip galvanized (HDG); contact Simpson Strong-Tie.

Installation:

• SSTB is used for monolithic and two-pour installations.
• Nuts and washers 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 (Simpson NUTB5/8-OST, NUT7/8-OST, CNW5/8-5/8OST, CNW7/8-7/8OST).

  Reinforced Concrete Foundation:

  • Install SSTB before the concrete pour using AnchorMates. Install the SSTB per plan view detail. Install one #4 rebar 3" to 5" (may be foundation rebar not post-tension cable) from the top of the foundation.
  • The SSTB does not need to be tied to the rebar.
  • Minimum concrete compression strength is 2500 psi. Unless noted otherwise, no special inspection is required for foundation concrete when the structural design is based on concrete no greater than 2500 psi (IBC Section 1704.4).
  • Unless otherwise noted, do NOT install where: (a) a horizontal cold joint exists within the embedment depth between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load, or the slab is designed to resist the load imposed by the anchor; or (b) slabs are poured over concrete block foundation walls.

  Reinforced Concrete Block:

  • Before concrete grout is poured, install diagonally at approx. 45° in the cell per plan view detail.
  • Horizontal #4 rebar (minimum 56" long centered about the anchor bolt) - approx. one rebar 12" from the top and two rebars approx. 28" from the top. Vertical #4 rebar (minimum 24" long) - install with maximum 24" o.c. spacing.
  • Grout all cells with minimum 2000 psi concrete. Vibrate the grout per the International Building Code, Section 2104.1.
