Strap Ties
Straps are designed to transfer tension loads in a wide variety of applications.
HRS - A 12 gauge strap with a nailing pattern designed for installation on the edge of 2x members. NEW! The HRS416Z installs with Simpson Strong-Tie® Strong Drive® screws (SDS).
LSTA and MSTA - Designed for use on the edge of 2x members, with a nailing pattern that reduces the potential for splitting.
LSTI - Light straps that are suitable where pneumatic-nailing is necessary through diaphragm decking and wood chord open web trusses.
MST - Splitting may be a problem with installations on lumber smaller than 3 1/2"; either fill every nail hole with 10dx1 1/2" nails or fill every-other hole with 16d common nails. Reduce the allowable load based upon the size and quantity of fasteners used.
MSTC - High Capacity strap which utilizes a staggered nail pattern to help minimize wood splitting. Nail slots have been countersunk to provide a lower nail head profile.
Finish: PS - HDG; HST3 and HST6 - Simpson Strong-Tie® gray paint; all others - galvanized. Some products are available in stainless steel or ZMAX® coating; see Corrosion Information.
Installation: Use all specified fasteners. See General Notes.
Options: Special sizes can be made to order. Contact Simpson Strong-Tie.
Codes: MSTC and RPS meet code requirements for reinforcing cut
members (16 gauge) at top plate and RPS at sill plate.
