This is a \u003cstrong\u003etimber screw\u003c\/strong\u003e designed for \u003cstrong\u003estructural wood-to-wood connections in exterior and treated wood applications\u003c\/strong\u003e. Model Number \u003cstrong\u003eSDWS221000DB\u003c\/strong\u003e. In this version, you get a 10 inch long screw with a 0.220 inch shank diameter, tan double-barrier coating, washer head, SawTooth point, and a 250-piece pack quantity.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw worth using instead of a traditional lag screw or through-bolt is the install speed. The SawTooth point is built to start fast and reduce installation torque, which means less fight from the driver and less time wasted predrilling in most jobs. If you're building ledger connections, outdoor structures, mass timber assemblies, or other structural framing where you need serious holding power without a slower bolt-up process, this screw is aimed right at that kind of work.\u003c\/p\u003e\n    \u003cp\u003eThe thread design matters here. Simpson calls out the bold thread geometry for superior holding power, and that is the whole point of this fastener category. You're not just pinning trim or decking. You're making structural connections in wood members where pull resistance and grip matter. The large washer head adds more bearing area at the surface, helping spread the load better than a smaller conventional head and improving clamp-down on the connected material.\u003c\/p\u003e\n    \u003cp\u003eDrive performance is another strong part of the design. The 6-lobe T40 drive gives more positive bit engagement than a basic slot or Phillips style head, which helps limit cam-out and lets you keep pressure on the screw during long drives. On a 10 inch fastener, that matters. Better engagement means less stripped heads, less bit wear, and fewer interruptions when you're sinking long screws into dense framing members or engineered wood.\u003c\/p\u003e\n    \u003cp\u003eSimpson also added underhead nibs so the head can seat flush with reduced splintering. That helps when you want a cleaner finish at the surface and do not want the head hanging proud. It is a practical feature, especially in visible outdoor work like pergolas, fencing, and timber details where the head needs to pull in cleanly without chewing up the surrounding wood fibers.\u003c\/p\u003e\n    \u003cp\u003eFor exterior use, the double-barrier coating is a big part of the value. Simpson states that it provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated wood applications as described in the evaluation report. That makes this screw a much better fit for outdoor framing, fencing, landscaping, and similar jobs than an uncoated interior-only fastener.\u003c\/p\u003e\n    \u003cp\u003eIn terms of real-world use, this \u003cstrong\u003eexterior wood screw\u003c\/strong\u003e is suited for structural wood-to-wood and engineered wood connections, including ledgers and mass timber connections such as wall-to-wall, floor-to-floor, surface splines, and lap joints. It is meant for contractors, builders, and serious DIY users who need a faster structural fastening option and do not want to mess with slower hardware where a code-recognized screw solution makes more sense.\u003c\/p\u003e\n    \u003cp\u003eIf you are choosing fasteners for outdoor framing or large wood assemblies, this is the kind of screw you buy when you care about drive speed, holding strength, and corrosion resistance in one package. It is not a finish screw and it is not pretending to be. It is a structural fastening solution built for big wood, long drive lengths, and jobs where a regular construction screw is out of its league.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eDrives Quickly Into Structural Lumber\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"row\"\u003e\n      \u003cdiv class=\"img\"\u003e\n        \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/10497949794598_984d24091dbf.jpg\" alt=\"Simpson Strong-Tie SDWS221000DB Strong-Drive SDWS Timber Screws (Exterior Grade) being driven into a ledger board during structural wood fastening on an exterior wall\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is built for long structural drives where install time matters.
