Simpson Strong-Drive® T27 DWP Wood SS Screws are structural fasteners built for long-lasting performance in demanding outdoor environments. Engineered for decks, docks, and boardwalks — especially in coastal or high-moisture areas — these stainless steel screws deliver code-tested holding power and exceptional corrosion resistance.

The proprietary box-thread design reduces driving torque, making installation faster and easier, while the sharp point cuts cleanly into hardwood and engineered materials. With Type 316 stainless steel options available, these screws are the go-to choice for severe exposure zones like marinas or waterfront structures.

Each pack includes a 6-lobe driver bit to keep installation precise and efficient, whether you're building new or maintaining existing structures.
