Simpson Strong-Tie STHD10 Strap Tie Holdown

The STHD is an embedded strap-tie holdown offering high loads and a staggered nail pattern to help minimize splitting. The STHD incorporates many features that aid correct installation and improve performance. When installed on the forms with the StrapMate strap holder, the unique design of the STHD delivers enhanced stability before and during the pour to help prevent both parallel and perpendicular movement (relative to the form). This results in accurate positioning of the strap and reduced possibility of spalling. Front-to-back concrete bond is strengthened by the slots below the embedment line and also aids in reducing spalling.
