This is a \u003cstrong\u003estructural wood screw\u003c\/strong\u003e designed for \u003cstrong\u003ewood-to-wood and engineered-wood connections\u003c\/strong\u003e. Model Number: \u003cstrong\u003eSDWS27600SS\u003c\/strong\u003e. If you are fastening ledgers, pier framing, boardwalk members, wharf components, or other exposed timber where corrosion resistance matters as much as holding power, this is the kind of fastener you spec on purpose.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw matter on the job is that it is meant to replace slower, more cumbersome fastening methods like spikes, lag bolts, lag screws, and in some cases through-bolting. The 0.275 inch shank diameter gives it the mass needed for structural applications, while the SawTooth point is designed for fast starts with no predrilling in most applications. Simpson also calls out that no counterboring is required for most installs, which cuts out a step and keeps crews moving.\u003c\/p\u003e\n    \u003cp\u003eThe head and drive design are doing real work here too. You get a 0.650 inch washer head that spreads load over a wider area than a typical screw head, and the nibs help the head seat flush with reduced splintering. That matters when you are fastening treated lumber, structural timbers, or decking assemblies and want a clean seat without chewing up the surface. The deep T50 6-lobe recess gives the driver bit more engagement, so you are less likely to strip the recess or deal with cam-out once resistance builds.\u003c\/p\u003e\n    \u003cp\u003eFrom a design standpoint, this is a purpose-built timber fastener, not just a long wood screw. The thread pattern, 3 inch thread length, washer head profile, and SawTooth point are all geared toward driving into substantial wood members efficiently. There is also mid-shaft knurling noted in supplementary product data to help reduce driving torque. On a long run of installs, anything that lowers resistance and keeps the screw tracking cleanly into the wood saves time and strain on both the tool and the user.\u003c\/p\u003e\n    \u003cp\u003eMaterial choice is a big reason to buy this version over a standard structural screw. The Type 316 stainless steel construction is intended for marine and coastal applications, including piers, boardwalks, wharves, and ledgers. In other words, this is the version you reach for when the environment is working against every fastener on site. Salt air, moisture, and harsh exposure are exactly where cheap hardware turns into callbacks.\u003c\/p\u003e\n    \u003cp\u003eOn the application side, Simpson lists this screw for structural wood-to-wood and engineered-wood connections. It is also part of a code-recognized fastening family for several wood framing and ledger-style applications, with published spacing and load information available from Simpson Strong-Tie. That is important for builders and remodelers who need a fastener that is not just convenient, but backed by actual technical data for real structural work.\u003c\/p\u003e\n    \u003cp\u003eThe specific SDWS27600SS version is 6 inches long with a 5 threads-per-inch pattern and packaging quantity of 300. That length gives you the reach needed for thicker members and heavier assemblies, while full-penetration guidance and published spacing requirements help with proper installation in structural lumber. If your work includes exterior framing, waterfront structures, deck ledger fastening, or heavy timber repairs in aggressive environments, this screw is built for that lane.\u003c\/p\u003e\n    \u003cp\u003eWho should buy it? Contractors, deck builders, marine carpenters, general contractors, and serious DIY users working on exposed structural wood assemblies. If you are doing interior trim or light-duty decking, this is overkill. If you are fastening structural members where corrosion, code, and long-term hold matter, the Simpson Strong-Tie SDWS27600SS Strong-Drive SDWS Timber SS Screw is the right kind of overbuilt.\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 Structural 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 SDWS27600SS Strong-Drive SDWS Timber SS Screw used in coastal pier deck construction on exposed structural lumber near the ocean\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is built for the kind of jobs that destroy ordinary fasteners.
