This is a heavy-duty connector screw designed for structural wood fastening where you want strength, faster installation, and less hassle than lag screws or bolts in many connector-driven applications. Model Number: SDS25112.\u003c\/p\u003e\n    \u003cp\u003eThe big selling point here is speed without giving up holding power. Simpson Strong-Tie uses a Type-17 point on the SDS25112, which helps the screw start easily with no predrilling and reduces wood splitting. On the job, that means fewer steps, less bit swapping, and cleaner installs when you are running a pile of connector screws into framing members.\u003c\/p\u003e\n    \u003cp\u003eThis screw is built around a 3\/8 inch hex drive and a hex head with a 0.500 inch integrated washer. That matters because the head gives you positive engagement with the driver, which helps when you are leaning into repetitive installs and do not want cam-out or stripped recesses. The integrated washer also spreads the bearing surface better at the connector face, which helps create a tight, secure connection.\u003c\/p\u003e\n    \u003cp\u003eThe thread design is just as important as the point. The SDS25112 uses serrated threads with 10 threads per inch and a 1 inch thread length. In practical use, that thread pattern helps the fastener bite and pull consistently into wood while still driving efficiently. For installers working on framing hardware, deck work, or structural wood connections, that translates to a screw that goes in cleaner and seats with less fighting.\u003c\/p\u003e\n    \u003cp\u003eFor exterior work, the Double-Barrier Coating is a key reason to pick this version. Corrosion resistance matters any time the screw is exposed to weather or used around treated lumber in approved conditions. If you are fastening heavy-duty Simpson Strong-Tie connectors outdoors, using the coated SDS version makes sense because you are matching the fastener to the real conditions it will live in, not just the day it gets installed.\u003c\/p\u003e\n    \u003cp\u003eJobsite practicality is another strong point. Simpson recommends installing SDS screws with a low-speed 1\/2 inch drill and a 3\/8 inch hex driver. That setup tells you exactly what kind of tool this fastener is meant to work with: not a delicate finish tool, but a proper drill that can deliver steady torque. The head is also stamped for identification after installation, which is one of those details you appreciate later when inspecting work or matching fasteners on larger projects.\u003c\/p\u003e\n    \u003cp\u003eAs far as fit and use, the SDS25112 is meant for heavy-duty Simpson Strong-Tie connectors and for wood-to-wood and engineered wood fastening where a short structural screw is the right length. At 1-1\/2 inches overall, this specific version is especially useful when you need structural holding strength in a shorter screw for connector applications instead of a longer timber screw.\u003c\/p\u003e\n    \u003cp\u003eIf you are a deck builder, carpenter, remodeler, or serious DIYer doing structural outdoor work, this is the kind of fastener that saves time and keeps the install straightforward. The Simpson Strong-Tie SDS25112 Strong-Drive SDS Heavy-Duty Connector Screw is a smart choice when you want a structural wood screw that drives fast, works with Simpson connector systems, and is built for exterior conditions.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eFast Structural Installs Without Predrilling\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 SDS25112 Strong-Drive SDS Heavy-Duty Connector Screw being driven into deck framing with a drill during exterior wood fastening on a jobsite\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is made to keep structural fastening moving.
