This is a structural wood screw designed for framing, remodeling, and engineered wood connections. Model Number: \u003cstrong\u003eSDWS16400Q\u003c\/strong\u003e. If you need a fastener that installs with a driver instead of swinging a hammer, while giving better holding power than nails in many framing applications, this is the kind of screw you buy on purpose.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw useful on the job is how it goes in. The SawTooth Type-17 point is built for fast starts and lower driving resistance, which helps eliminate predrilling in most applications. That saves time when you are running repetitive framing connections, fastening lumber, or tying members together in remodeling work. The serrated threads also help reduce installation torque, so the screw drives more efficiently and does not fight the tool as much on the way in.\u003c\/p\u003e\n    \u003cp\u003eThe head design matters here too. Simpson uses a low profile washer head with underhead box nibs, which increases bearing surface in structural applications and helps the head seat cleanly into the wood. In plain terms, you get more clamp area than a small bugle head or typical deck screw head, which is exactly what you want when the fastener is doing real structural work. The T25 6-lobe drive also gives positive bit engagement, reducing cam-out and helping bits last longer during high-volume fastening.\u003c\/p\u003e\n    \u003cp\u003eFor jobsite conditions, the Quik Guard coating is a big part of the value. It is intended for indoor and outdoor applications, so this framing screw works across general construction, exterior projects, and many everyday structural wood connections without stepping up to a more specialized stainless fastener. The carbon steel body provides the strength you expect from a structural screw, while the coating adds the corrosion protection needed for broader use than a basic interior-only fastener.\u003c\/p\u003e\n    \u003cp\u003eThis specific SDWS16400Q version is the 4 inch length option with a 0.450 inch head diameter, 0.160 inch shank diameter, 8-1\/2 threads per inch, and 2-1\/2 inch thread length. Those numbers matter because they tell you this screw is sized for real framing and wood member tie-ins, not light trim work. The longer body gives you reach for thicker stock and stronger embedment, while the thread geometry is set up for wood-to-wood grab rather than metal fastening.\u003c\/p\u003e\n    \u003cp\u003eIf you are a framer, remodeler, contractor, or serious DIYer working on structural wood assemblies, this is the right kind of fastener when you want speed, strong holding power, and easier installation with an impact driver or drill\/driver. It is especially useful for wood framing, engineered wood applications, and indoor or outdoor projects where a code-listed framing screw makes more sense than a common nail or a generic construction screw.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-1\" class=\"acc\" open\u003e\n  \u003csummary\u003e\u003ch2\u003eFast Starts in Framing 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:\/\/ssttoolbox.widen.net\/content\/e5jdvinghx\/jpeg\/F_SDWS16_InstPho_Pho_Inst_SDWS-FramingScrew-Beam_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie SDWS16400Q Strong-Drive SDWS Framing Screw being driven into framing lumber on a workbench during wood-to-wood fastening in a shop setting\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is built to move through framing work without a lot of drama.
