This is a \u003cstrong\u003estructural wood screw\u003c\/strong\u003e designed for \u003cstrong\u003efastening wood-to-wood connections in exterior framing and timber applications\u003c\/strong\u003e. Model Number \u003cstrong\u003eSDWS22800DB\u003c\/strong\u003e. In this version, you get an 8 inch tan screw with a 0.220 inch shank and a pack quantity of 400, making it a practical choice for contractors, crews, and serious DIYers who need repeatable structural fastening without moving over to through-bolting or traditional lag screws.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw matter on the job is how it installs. Simpson uses a SawTooth point that helps the screw start fast, reduces installation torque, and eliminates predrilling in most applications. On long fasteners, that matters. Less predrilling means less time per connection, less battery drain, and less frustration when you're sinking screws into dense framing members, ledgers, posts, or heavy landscape timbers. The 6-lobe T40 drive also gives positive bit engagement, which helps reduce cam-out and improves bit life compared to lower-engagement drive styles.\u003c\/p\u003e\n    \u003cp\u003eThe head and thread design are doing real work here too. The large washer head creates a broad bearing surface, which helps clamp material securely in structural wood fastening. Underhead nibs help the head drive flush with reduced splintering, so you get a cleaner seat at the surface instead of tearing up the top layer of the board. Simpson also marks size identification on the screw head, which is a small feature until you're sorting mixed fasteners on site and need to know what you're holding without guessing.\u003c\/p\u003e\n    \u003cp\u003eFor outdoor and treated-lumber work, the double-barrier coating is one of the main reasons to buy this version. Simpson states the coating provides corrosion resistance equivalent to hot-dip galvanization for certain exterior and preservative-treated wood applications as described in the evaluation report. That makes this screw a better fit for exterior structural wood projects than a standard interior fastener. If you're building decks, ledgers, fence framing, pergolas, planter boxes, or other exposed wood assemblies, the coating is not just a spec on paper. It is the difference between using the right structural fastener and using something that was never meant to live outdoors.\u003c\/p\u003e\n    \u003cp\u003eThe 8 inch length gives you reach for thicker assemblies where a shorter structural screw will not get enough bite into the receiving member. At the same time, the 3 inch thread length and 0.220 inch shank are set up for structural holding in wood applications rather than light-duty fastening. This screw is part of Simpson Strong-Tie's Strong-Drive SDWS TIMBER line, which is used in structural wood-to-wood and engineered wood connections including ledgers and certain mass timber connections such as CLT wall-to-wall, floor-to-floor, surface splines, and lap joints.\u003c\/p\u003e\n    \u003cp\u003eWho should buy it? Contractors building exterior wood structures, deck builders handling ledger fastening, carpenters working with posts and beams, and serious DIY users who want a structural alternative to lag screws. If you need an 8 inch exterior wood screw that installs faster than old-school lag hardware and still gives you the kind of holding power expected in structural work, this is exactly the lane this screw is built for.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eFaster Structural Wood Fastening\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\/10497950056742_984d24091dbf.jpg\" alt=\"Simpson Strong-Tie SDWS22800DB Strong-Drive SDWS Timber Screw being driven into a ledger board for exterior wood-to-wood fastening during framing work\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is made to speed up structural fastening in wood without the usual predrill routine that slows down ledger and framing work.\u003c\/p\u003e\n        \u003cul\u003e\n          \u003cli\u003eSawTooth point helps ensure fast starts 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\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-2\" class=\"acc flip\"\u003e\n  \u003csummary\u003e\u003ch2\u003eMade for Outdoor Builds\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\/10497950056742_5aa57a4f40ee.jpg\" alt=\"Simpson Strong-Tie SDWS22800DB Strong-Drive SDWS Timber Screw used to fasten pergola framing outdoors in exposed wood construction\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eFor exterior framing, pergolas, and treated-lumber projects, coating matters.
