Ideal for decking applications, the Simpson Strong-Tie trim-head screw features a square drive for secure, slip-free engagement during installation. The low-profile, trim-style head sits flush with the surface, delivering a clean finish. A Type-17 point allows for quick starts, while coarse threads on the lower two-thirds of the shank provide powerful pull-throughdrawing deck boards tightly to the joists for a secure hold. Simpson Strong-Tie offers this trim-head screw in stainless steel 6-lobe drive (and painted heads) for hand-drive applications, as well as in collated square-drive versions (with and without painted heads) for the Simpson Strong-Tie Quik Drive auto-feed screw driving systems.
