HRS/ST/FHA/PS/LSTA/LSTI/MST/MSTA/MSTC/MSTI Strap Ties

HRS/ST/FHA/PS/LSTA/LSTI/MST/MSTA/MSTC/MSTI

Straps are load rated and provide the correct thickness and number of fasteners the specifier is looking for compared with field-fabricated straps.

Install strap ties where top or bottom plates are cut, at wall intersections, and as ridge ties. Reduce the allowable load based on the size and quantity of fasteners used.

Refer to applicable code for minimum edge and end distances.

Finish

  • PS — hot-dip galvanized (HDG); all others — galvanized. Some products are available in stainless steel or ZMAX®. See Corrosion Information.

Installation

  • Use all specified fasteners; see General Notes

Related Literature

Product Information Tables

  1. PS strap design loads must be determined by the Designer for each illustration. Hole diameter in the part may be oversized to accommodate the HDG. Designer must determine if the oversize creates an unacceptable installation.

Load Tables

    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. Use half of the fasteners in each member being connected to achieve the listed loads.
  2. Loads are based on lesser of steel capacity or fastener calculation.
  3. Not all fastener holes need to be filled as additional fastener holes are provided. Install fasteners symmetrically.
  4. See more on Simpson Strong-Tie fasteners.
