#7 x 3″ Simpson Strong-Tie #1 Square Drive Trim Head Deck Screw – 316 Stainless, Pkg. 5 Lb.

The Simpson Strong-Tie Trim-Head Square Drive Wood Screw is built for decking applications where both strength and appearance matter. Designed with a low-profile trim head that sits flush with the surface, it provides a clean, professional look while holding deck boards securely in place. A Type 17 point ensures fast starts, and coarse threads along the shank pull boards tightly to joists for a strong, lasting connection.

Engineered for reliability, these screws feature a square-drive recess for slip-free engagement that reduces cam-out and speeds up installation. Engineered in Type 316 stainless steel for corrosion resistance, theyre also offered in collated strips for Quik Drive systems and in hand-drive versions with optional painted heads for seamless finishes.
