This is a structural wood screw designed for wood-to-wood fastening in marine and exterior timber applications. Model Number: \u003cstrong\u003eSDWS271000SS-R30\u003c\/strong\u003e. If you are building or repairing piers, boardwalks, wharves, ledgers, or other exposed timber assemblies, this fastener is built for that kind of work.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is not just the length. The 0.275 inch shank diameter puts this screw into true structural territory, making it a practical alternative to spikes, lag bolts, and lag screws where you want strong holding power without the extra labor that usually comes with traditional large fasteners. Simpson Strong-Tie also calls out that no predrilling and no counterboring are required for most applications, which can save real time when you are driving a lot of fasteners into dense framing or large timber members.\u003c\/p\u003e\n      \u003cp\u003eThe business end is set up to work, not just look good on paper. The SawTooth point is designed for fast starts, which helps the screw bite quickly and get moving without wandering. That is especially useful when you are working on weathered lumber, treated wood, or awkward exterior assemblies where you do not want to fight the fastener just to get it started. The thread design and heavy shank make this screw a better fit for structural fastening than a standard wood screw.\u003c\/p\u003e\n      \u003cp\u003eDrive performance is another big part of why this fastener makes sense on the job. The deep T50 6-lobe recess gives you a more secure bit fit than shallow drive recesses that cam out under load. When you are sinking a long 10 inch timber screw, that matters. Better engagement means more control, less stripping, and less wasted time swapping damaged bits or backing out half-driven screws. Simpson Strong-Tie lists the replacement driver bit as BIT50T-2-R1.\u003c\/p\u003e\n      \u003cp\u003eThe head design is built around installation quality. This model uses a washer head with nibs that can drive flush to the wood surface while reducing splintering. That gives you broad bearing at the surface, which is important in wood-to-wood structural connections, and it helps the finished installation sit cleaner than you would expect from a fastener this substantial. The listed head diameter is 0.650 inch, so you are getting meaningful surface contact at the connection point.\u003c\/p\u003e\n      \u003cp\u003eMaterial choice is the whole reason this specific version exists. This screw is made from Type 316 stainless steel, which is intended for coastal and severe corrosion conditions. That makes it a smart choice anywhere salt air, moisture, or marine exposure would quickly chew through lesser fasteners. Simpson Strong-Tie specifically identifies applications such as piers, boardwalks, wharves, and ledgers, which tells you exactly where this product belongs.\u003c\/p\u003e\n      \u003cp\u003eFor the buyer, the takeaway is simple. If you need a long stainless timber screw for structural wood fastening where corrosion resistance is non-negotiable, this is the right kind of fastener. It is aimed at contractors, marine builders, deck builders, and serious property owners working on exposed exterior timber structures. If your project is inland and dry, there may be lower-cost options. If your project lives near the ocean or in harsh wet conditions, this is the version you want to be looking at.\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\u003eMade for Coastal Timber Work\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:\/\/ssttoolbox.widen.net\/content\/tzpwrx4bih\/jpeg\/F_SDWS27xxxSS_InstPho_Pho_Inst_TIMBER-StanlessSteelScrew-PismoPierConstruction-1_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie SDWS271000SS-R30 Strong-Drive SDWS TIMBER SS Screw used in pier construction on an oceanfront jobsite for marine wood-to-wood fastening\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis screw is built for the kind of exposed timber work that destroys ordinary fasteners.
