This is a wood screw designed for structural wood-to-wood connections, including ledgers. Model Number: \u003cstrong\u003eSDWH19600DB\u003c\/strong\u003e. If you need a long fastener that installs faster than traditional lag screws in many common wood jobs, this is the one built for that kind of work.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw matter is how it goes in. Simpson uses a SawTooth point that helps the screw start fast, cuts installation effort, and eliminates the need for predrilling in most applications. On a real job, that saves time on repetitive fastening and makes it easier to keep production moving when you are working on deck framing, ledger attachment, pergolas, planters, or heavy exterior wood assemblies.\u003c\/p\u003e\n    \u003cp\u003eThe thread design is another big part of the story. The bold thread profile is there for holding power, not just for looks on a spec sheet. When you are fastening thick members together, you want the screw to pull material tight and stay put. The large hex washer head adds more bearing area at the surface, which helps reduce pull-through and gives the connection a more secure seated feel in structural wood applications.\u003c\/p\u003e\n    \u003cp\u003eThe head and drive setup are jobsite friendly. This screw uses a 5\/16 inch hex drive, which gives positive engagement and better control than a lot of smaller drive styles when you are pushing a long fastener into dense lumber. The underhead nibs help the head countersink into wood with reduced splintering, so you get a cleaner finished seat instead of a ragged surface around the head.\u003c\/p\u003e\n    \u003cp\u003eFor exterior work, the coating matters just as much as the geometry. This SDWH Timber-HEX screw uses Simpson's double-barrier coating, which the manufacturer states provides corrosion resistance equivalent to hot-dip galvanization for certain exterior and preservative-treated wood uses described in the evaluation report. If you are building outdoors, fastener finish is not a throwaway detail. It directly affects service life and long-term connection reliability.\u003c\/p\u003e\n    \u003cp\u003eSize-wise, this specific version is 0.195 inch shank diameter by 6 inches long with a 0.650 inch head diameter, 6 threads per inch, and 2-3\/4 inch thread length. That combination gives you a long body for deeper structural reach while keeping the aggressive threaded section where it can do the pulling. It is well suited for thicker wood members where a short screw simply is not enough.\u003c\/p\u003e\n    \u003cp\u003eThe Simpson Strong-Tie SDWH19600DB Strong-Drive SDWH Timber-HEX Screw is a smart buy for deck builders, framers, remodelers, general contractors, and serious DIY users who want a structural exterior wood screw with faster install and strong holding power. If your work is mostly wood-to-wood fastening and you prefer a hex-head drive over a socket or wrench-driven lag setup, this screw makes a lot of sense.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eDrive Structural Screws Without the Usual Fight\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\/1eaxvl6dwj\/jpeg\/F_SDWH-DB_InstPho_Pho_Inst_SDWH-TimberHexScrew-Ledger-wDrill_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie SDWH19600DB Strong-Drive SDWH Timber-HEX Screw being driven into a deck ledger board during exterior wood-to-wood fastening on a jobsite\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eLong structural screws are only useful if they install cleanly.
