This is a heavy-duty connector screw designed for fastening Simpson Strong-Tie connectors and other structural hardware into wood without predrilling. Model Number: \u003cstrong\u003eSDS25112MB\u003c\/strong\u003e. This version gives you a 1-1\/2 inch length, double-barrier coating, and a 300-count package for repetitive install work.\u003c\/p\u003e\n    \u003cp\u003eWhat matters here is speed and consistency. The Type-17 point is built to start easier in wood, which cuts down on the need for pilot holes and helps reduce splitting. On the job, that means faster installs when you are hanging hardware, tying framing members together, or setting exterior structural connectors where you want a strong mechanical connection without the extra step of predrilling every fastener location.\u003c\/p\u003e\n    \u003cp\u003eThe head and thread design are doing real work too. This screw uses a 3\/8 inch hex head with a 0.500 inch integrated washer, so you get better bearing at the connection point than you would with a smaller conventional head. The serrated threads help the screw drive more efficiently, which is one reason these are popular for connector work where clean seating and repeatable drive performance matter.\u003c\/p\u003e\n    \u003cp\u003eFor outdoor and exposed applications, the double-barrier coating is a big part of the value. It gives the screw added corrosion resistance compared with plain interior fasteners, which makes it a practical choice for deck-related work, exterior framing, and other projects where moisture is part of the environment. If you are matching the fastener to exterior-rated hardware, this coating is one of the reasons the SDS line is commonly specified.\u003c\/p\u003e\n    \u003cp\u003eThis fastener is also built around jobsite practicality. The head is stamped with the Simpson Strong-Tie identification mark and the fastener length, which makes it easier to verify what was installed after the fact. That sounds small until you are inspecting a connection, sorting leftover hardware, or coming back to a project later and need to know exactly what is in the assembly.\u003c\/p\u003e\n    \u003cp\u003eThe Simpson Strong-Tie SDS25112MB Strong-Drive Heavy-Duty Connector Screw installs with a low-speed 1\/2 inch drill and a 3\/8 inch hex driver. It is also compatible with replacement driver bit \u003cstrong\u003eBITHEXR38-R1\u003c\/strong\u003e. That makes it easy to fit into a standard structural fastening setup without hunting down a specialty drive system.\u003c\/p\u003e\n    \u003cp\u003eWho should buy it? Contractors, deck builders, remodelers, framers, and serious DIY users who are installing Simpson Strong-Tie connectors or doing structural wood fastening outdoors. If you need a general light-duty wood screw, this is more screw than you need. If you need a fast, strong, no-nonsense structural connector screw that saves time over predrilled lag-style installs, this is exactly the lane it belongs in.\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\u003eFaster Structural 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:\/\/ssttoolbox.widen.net\/content\/hzlr7w8cxn\/jpeg\/F_SDS_InstPho_Pho_Inst_SDS-HeavyDutyConnectorScrew-Deck-wDrill_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie SDS25112MB Strong-Drive Heavy-Duty Connector Screw being driven into deck framing with a drill during exterior wood fastening\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is built to keep connector installs moving.
