Each screw measures 5 inches in length by 5\/16 inches in diameter and features a Type 17 cut point for easier starts in dense or treated lumber without pre-drilling. The star drive head reduces cam-out during installation. A coarse, serrated thread pattern provides strong pull-through resistance. The bronze ceramic coating is tested to 1500 hours of salt spray resistance, making these lags well-suited for corrosive or exterior environments.\u003c\/p\u003e\u003cp\u003eThese construction lags are intended for use in residential and light commercial structural fastening applications, including deck framing, ledger board attachment, post connections, and treated lumber assemblies. The corrosion-resistant ceramic coating makes them appropriate for ground-contact-adjacent and coastal installations where standard zinc-coated fasteners would degrade quickly. They are commonly installed by carpenters, deck builders, and general contractors working to current building codes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 17 cut point starts in dense and treated lumber without pilot hole in many applications\u003c\/li\u003e\n\u003cli\u003eStar drive recess minimizes cam-out and improves torque transfer\u003c\/li\u003e\n\u003cli\u003eCoarse, serrated thread pattern for high pull-through and withdrawal resistance\u003c\/li\u003e\n\u003cli\u003eBronze ceramic coating rated to 1500 hours of salt spray resistance\u003c\/li\u003e\n\u003cli\u003eLifetime warranty coverage\u003c\/li\u003e\n\u003cli\u003e75 screws per pack for high-volume framing and structural tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as OEM-style structural lag screws suitable for use in wood framing, deck construction, and treated lumber fastening applications where corrosion resistance is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, deck builders, or licensed contractors using a star-bit driver and a heavy-duty impact driver or drill. Always consult applicable building codes, including the IRC or IBC, for required fastener schedules, embedment depths, and spacing in structural connections. Power down and secure the work area before drilling into existing structural members. Do not substitute these fasteners in applications requiring engineer-specified hardware without verification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Star\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type 17 Cut Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse, Serrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bronze Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSalt Spray Rating\u003c\/strong\u003e: 1500 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 75 screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN FASTENERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51560159510834,"sku":"47878","price":267.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa44155c7be53df3783b3f2d9dd31201_2fcf8cc5-a533-4083-8654-06765e53544d.jpg?v=1786447799","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-47878-construction-lag-screws-75-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
