DB Coating, 200-Pack (SDS25212MB) is a high-strength structural wood screw made for connector fastening, wood-to-wood fastening, and engineered wood applications. This is a heavy-duty connector screw designed for structural fastening in wood framing and connector installations. Model Number: SDS25212MB.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this screw different from a standard wood screw is that it is built specifically for demanding structural work. The 1\/4 in. diameter body gives it the strength expected for connector and framing applications, while the Type-17 point helps it start quickly without predrilling. On the job, that means faster installs and less hassle when you are driving into framing members, ledgers, or hardware locations where productivity matters.\u003c\/p\u003e\n    \u003cp\u003eThe Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector Screw uses serrated threads to bite into the wood and pull the fastener in with solid holding power. That thread design is there for more than just grip. It also helps the screw drive more efficiently, which is useful when you are installing multiple fasteners in a row across connectors, deck framing, or general structural wood fastening. The 2-1\/2 in. overall length with 1-1\/2 in. thread length makes this particular version a practical middle size for many common heavy connector and framing tasks.\u003c\/p\u003e\n    \u003cp\u003eThe head design is equally important here. You get a 3\/8 in. hex drive with a 0.500 in. integrated washer under the hex head. In plain terms, that gives you a broad bearing surface and a secure drive interface that is less likely to cam out than smaller recess styles. If you are working with structural connectors or fastening into lumber in awkward positions, a hex head is the kind of detail that makes the install more controlled and more repeatable.\u003c\/p\u003e\n    \u003cp\u003eFor exterior work, the double-barrier coating is a key reason to choose this version. Simpson lists it as corrosion-resistant, which makes it better suited for outdoor framing and exposed wood applications than plain interior fasteners. If you are building or repairing deck structures, mounting hardware to framing, or installing approved Simpson Strong-Tie connectors, this coating helps the fastener hold up better over time.\u003c\/p\u003e\n    \u003cp\u003eThis screw is also built with jobsite identification in mind. The head is stamped with the Simpson Strong-Tie mark and fastener length, which sounds minor until you are coming back to an installed assembly and need to verify what was used. That can save time during inspections, punch-list work, or when matching existing installed hardware on additions and repairs.\u003c\/p\u003e\n    \u003cp\u003eFor installation, Simpson recommends a low-speed 1\/2 in. drill with a 3\/8 in. hex driver. There is also a replacement driver bit available, model BITHEXR38-R1, which is worth knowing if you keep structural fasteners stocked in the shop or trailer. This is not a finish screw or a general-purpose cabinet screw. It is purpose-built fastening hardware for structural wood work where connector compatibility, drive strength, and holding performance matter.\u003c\/p\u003e\n    \u003cp\u003eWho should buy it? Contractors, deck builders, framers, remodelers, and serious DIY users working with structural connectors or demanding wood fastening jobs. If you need a fastener for heavy-duty Simpson Strong-Tie connectors, deck framing, or structural wood-to-wood work and you want a screw that installs fast without predrilling, this is exactly the kind of screw you buy by the box and keep on hand.\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 in Wood\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:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/10497948451110_9f1dc0541113.jpg\" alt=\"Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector Screw, 1\/4-in. x 2-1\/2-in.
