The Simpson Strong-Tie Trim-Head Square Drive Decking Screw is designed to deliver strength and a clean finish in decking applications. Featuring a low-profile trim head that sits flush with the surface, these screws provide a professional look while securely fastening deck boards.

Engineered for easy installation, the screw uses a square-drive recess for secure, slip-free engagement that reduces cam-out and improves driving efficiency. A Type 17 point ensures fast starts, while coarse threads along the shank pull boards tightly to joists for a secure, long-lasting hold. Painted head options and collated versions for Quik Drive® auto-feed systems are also available.
