Each screw features a galvanized base with a PrimeGuard Plus coating that closely matches the color of treated lumber, keeping fasteners visually consistent with the finished surface. The flat countersinking head sits flush on installation, and the Type 17 drill tip drives directly into wood without pre-drilling. High corrosion resistance makes these screws suitable for long-term exterior exposure in demanding conditions.\u003c\/p\u003e\n\u003cp\u003eThese screws are built for all exterior wood applications where corrosion resistance and holding strength are priorities. The extra-coarse thread pattern reduces wood splitting and lowers driving friction, speeding up installation on large projects. Typical use cases include deck boards, dock framing, fence pickets, and gazebo structures. The coating is compliant for use with treated lumber, making these a direct fit for pressure-treated construction where standard zinc-plated fasteners would corrode prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized base with PrimeGuard Plus coating for high corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eType 17 drill tip eliminates the need for pre-drilling in most wood applications\u003c\/li\u003e\n  \u003cli\u003eExtra-coarse thread pattern reduces splitting and driving friction\u003c\/li\u003e\n  \u003cli\u003eFlat countersinking head sits flush with the wood surface\u003c\/li\u003e\n  \u003cli\u003eCoating color matches treated lumber for a consistent finished appearance\u003c\/li\u003e\n  \u003cli\u003eCompliant for use with treated lumber\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for exterior wood fastening applications including decks, docks, fences, and gazebos using treated or untreated dimensional lumber.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThese screws are installed by licensed carpenters, general contractors, and experienced DIYers working on exterior wood structures. The Type 17 tip allows direct driving with a power drill or impact driver fitted with a combo bit — no pilot hole required in most softwood and treated lumber. Follow local building codes for fastener spacing and shear requirements on structural deck framing. Avoid over-driving, which can compromise the countersink and reduce holding strength at the surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Combo (combination drive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Flat countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Extra coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Type 17 drill tip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Galvanized base with PrimeGuard Plus finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1-pound box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Exterior wood including treated lumber\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DO IT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 729974\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DO IT BEST","offers":[{"title":"Default Title","offer_id":51718683459890,"sku":"729974","price":18.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/876d0b6092d20fd0efa97f91b3871833.jpg?v=1788554981","url":"https:\/\/voomisupply.com\/products\/do-it-729974-exterior-combo-drive-deck-screws-2-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
