Simpson Strong-Tie S07250FB5 Trim-Head Screw, Square Drive — #7 x 2-1/2 in. #1 SQ, Type 305 (5 lb.)

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-through—drawing 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.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
