The Simpson Strong-Tie STHD is an embedded strap-tie holdown designed to deliver high loads in both wood and cold-formed steel construction. When installed on forms using the StrapMate® strap holder, the STHD provides enhanced stability before and during the pour — preventing both parallel and perpendicular movement for accurate positioning and reduced spalling risk.
Staggered nailing patterns minimize splitting when nailing to edges of double 2x members. Countersunk strap nail slots provide a lower nail head profile for a cleaner connection. The slots below the embedment line increase front-to-back concrete bond.
