Deck Screws

Deck screws are purpose-built fasteners that deliver long-lasting hold, clean finishes, and fewer callbacks on outdoor projects. Compared to nails, decking screws offer superior pull-out resistance, reduce squeaks, and minimize board movement through seasons. Choose materials that match your site: stainless steel deck screws (305 for general use, 316 for coastal and salt-spray zones) provide top corrosion resistance, while polymer or ceramic-coated steel screws handle most pressure-treated framing at a friendlier price. Common sizes are #8 or #10 in 2-1/2 in. for 5/4 boards and 3 in. for 2x decking to joists.

Modern features speed installation and protect your work. A Type 17 self-drilling tip starts fast and limits splitting, aggressive threads bite securely, and bugle or trim heads seat flush without crushing fibers. Composite deck screws often add cutters or reverse threads to prevent mushrooming, with color-matched heads for a seamless look. Star/Torx (often T-25) or square-drive recesses reduce cam-out and bit slips, extending bit life and keeping heads intact. Hidden deck fastener systems and plug kits are available if you want a screw-free surface.

Smart selection and technique pay off. For cedar, redwood, and tropical hardwoods like ipe, opt for stainless and pre-drill near board ends. For ACQ pressure-treated lumber, use coated deck screws rated for chemical compatibility. Drive two screws per joist, keep edge and end distances consistent, and consider a countersink for hardwoods. Use an impact driver with quality bits, set clutch or torque thoughtfully, and keep a straight drive angle to avoid broken heads. Check local codes and manufacturer guidance for span, spacing, and fastener requirements. Whether you are building a new deck, replacing boards, or tightening a noisy step, the right decking screws deliver durability, safety, and a professional finish.
