The Simpson Strong-Tie SDS structural screw delivers high-strength performance for wood-to-wood and engineered-wood connections. An improved Type-17 point drives easily with no predrilling, reducing splitting and speeding installation. Each screw features a 3/8" hex head with an integrated washer and a corrosion-resistant epoxy finish, making these screws ideal for deck ledger connections, guardrail attachments, and heavy-duty connector applications. Packaged in a convenient 25-count box, SDS screws are stamped for quick identification on the jobsite and offer serrated threads to maximize holding power.

With extensive testing behind every fastener, you can trust Simpson Strong-Tie SDS screws to secure your outdoor living structures and critical framing elements.
