This is a structural wood screw designed for fastening wood-to-wood connections in exterior applications. Model Number: \u003cstrong\u003eSDWS221000DB-R50\u003c\/strong\u003e. If you are building ledgers, posts, beams, pergolas, fences, or other structural connections and want a faster alternative to through-bolting or old-school lag screws, this is the kind of fastener you reach for.\u003c\/p\u003e\n\u003cp\u003eWhat matters most on the job is how a screw starts, how it drives, and how well it holds. Simpson uses a SawTooth point here, which helps the screw start fast, cuts down installation torque, and eliminates predrilling in most applications. The bold thread design is there for holding power, not marketing copy. It helps the screw pull tight and stay locked in wood members where a weak or shallow thread would give up ground.\u003c\/p\u003e\n\u003cp\u003eThe head and drive setup are also well thought out. This version uses a large washer head with a 0.760-inch diameter, so you get a broad bearing surface that helps clamp material without needing a separate washer. Underhead nibs help the head seat flush with less splintering at the surface, which matters when you want a clean finished look on exposed framing or outdoor structures. The 6-lobe T40 drive gives positive engagement, so the bit stays planted better under load and you spend less time fighting stripped recesses.\u003c\/p\u003e\n\u003cp\u003eFor this specific variant, the screw is 10 inches long with a 0.220-inch shank diameter and a 3-inch thread length. That combination makes it useful where you need long reach through thick assemblies while still getting the grip and pull of a structural screw. The tan double-barrier coating is meant for exterior use and for certain preservative-treated wood applications. In plain terms, this is the better fit when standard interior fasteners are not enough and you need a screw that can live outside.\u003c\/p\u003e\n\u003cp\u003eSimpson positions the Strong-Drive SDWS TIMBER screw for structural wood-to-wood and engineered wood applications, including ledgers and mass timber connections such as wall-to-wall, floor-to-floor, surface splines, and lap joints. That tells you this is not just a landscaping screw or a deck trim fastener. It is meant for real structural fastening where code-listed hardware and predictable performance matter.\u003c\/p\u003e\n\u003cp\u003eWho should buy it? Contractors, framers, deck builders, remodelers, and serious DIY users working on exterior structures. If you need a 10-inch exterior structural screw in a 50-count pack and want easier installation than traditional lag screws, the Simpson Strong-Tie SDWS221000DB-R50 lands in the sweet spot. It is especially useful when speed matters, access is tight, and you still need a strong mechanical connection in wood.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eMake Ledger and Beam Connections Faster\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/10497949860134_984d24091dbf.jpg\" alt=\"Simpson Strong-Tie SDWS221000DB-R50 Strong-Drive SDWS TIMBER Screw being driven into a wood ledger during exterior structural fastening\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThis screw is built for the kind of wood-to-wood structural fastening that can eat up time if every fastener needs a pilot hole and a wrench.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSawTooth point helps the screw start quickly and reduces installation torque\u003c\/li\u003e\n\u003cli\u003eDesigned as an alternative to through-bolting and traditional lag screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-2\" class=\"acc flip\"\u003e\u003csummary\u003e\u003ch2\u003eHold Tight Without Beating Up the Surface\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/10497949860134_01a2edf64ead.jpg\" alt=\"Simpson Strong-Tie SDWS221000DB-R50 Strong-Drive SDWS TIMBER Screw fastening horizontal rails to a post on an outdoor wood fence\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThe big washer head does more than look different.
