Specifications
Simpson Strong-Tie SDWS Exterior Grade Timber Screws are engineered for high-strength structural wood-to-wood and engineered wood (EWP) connections. Designed for demanding outdoor applications, these screws deliver the holding power and durability professionals rely on when building decks, pergolas, framing systems, and other load-bearing structures.
The tan coated finish is specifically developed to provide superior corrosion resistance in exterior environments while blending seamlessly with treated lumber for a clean, professional appearance. Featuring a patented thread design and optimized tip geometry, SDWS screws drive fast, reduce splitting, and eliminate the need for pre-drilling in most applications. Whether you're working with solid sawn lumber or engineered wood products, these screws provide a secure, code-recognized fastening solution built for long-term performance.
