Description

A heavy-duty structural wood screw from Simpson Strong-Tie's Strong-Drive Screw (SDS) series, designed for robust wood-to-wood or wood-to-metal construction connections. Features a hex head for high-torque driving, a sharp point for easy installation (often without pre-drilling), and an engineered shank for excellent shear and withdrawal resistance. Often coated for corrosion resistance, suitable for interior and exterior use. Used for fastening ledger boards, deck posts, and other structural lumber.
