Description
Straps are designed to transfer tension loads in a wide variety of applications.
HRS — heavy strap designed for installation on the edge of 2x members. The HRS416Z installs with Strong-Drive® SDS Heavy-Duty Connector screws.
HTP — heavy tie plate designed for installation on the side of 2x4 or larger members.
LSTA and MSTA — designed for use on the edge of 2x members, with a nailing pattern that reduces the potential for splitting.
LSTI and MSTI — light and medium straps that are suitable where pneumatic nailing is necessary through diaphragm decking and wood chord open-web trusses.
MST — high-capacity strap that can be installed with either nails or bolts. Suitable for double 2x member connections or greater.
MSTC — high-capacity strap that utilizes a staggered nail pattern to help minimize wood splitting. Nail slots have been countersunk to provide a lower nail head profile.

- See General Notes for Straps and Ties.
- Install bolts or nails as specified by Designer. Bolt and nail values may not be combined.
- Allowable bolt loads are based on parallel-to-grain loading and minimum member thickness: MST — 2 1/2".
- Splitting may be a problem with installations on lumber smaller than 3 1/2"; either fill every nail hole with 0.148" x 1 1/2" nails or fill every other hole with 0.162" x 2 1/2" nails. Reduce the allowable load based on the size and quantity of fasteners used.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
- See General Notes for Straps and Ties.
- Allowable bolt loads are based on parallel-to-grain loading and these minimum member thicknesses: HST2 and HST5 — 3 1/2"; HST3 and HST6 — 4 1/2".
