Featuring a hex washer head and hex drive, this screw delivers high torque transfer and a broad bearing surface that resists pull-through. The No. 3 drill point eliminates the need for a pilot hole in light-gauge steel. Each screw measures 3 inches under the head and carries a 12-14 thread pitch. Sold in a 100-piece package, the 560039 is a standard supply item for sheet metal mechanics, HVAC installers, and general contractors.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light commercial and residential construction where fastening into light-gauge steel framing, ductwork, metal decking, or similar substrates is required. The No. 3 drill point is rated for penetrating thicker steel gauges than a No. 2 point, making it appropriate for structural attachments and heavier sheet metal assembly. HVAC technicians commonly use this fastener for duct connections, equipment mounting, and metal trim work where a secure, weather-resistant hex washer head seating is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 3 drill point drills its own pilot hole in light-to-medium gauge steel without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides a wide bearing surface and resists pull-through under load\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 5\/16-inch hex driver bits for high-torque power tool use\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits deeper substrate fastening and multi-layer assemblies\u003c\/li\u003e\n  \u003cli\u003eNo. 12-14 thread size delivers strong thread engagement in steel applications\u003c\/li\u003e\n  \u003cli\u003e100-piece package quantity supports job-site and shop inventory efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard No. 12 self-drilling screw for use with light-gauge steel framing, sheet metal ductwork, and similar metal substrates requiring a No. 3 drill point fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified HVAC technicians, sheet metal mechanics, or electricians familiar with self-drilling fastener applications. Use a hex-drive bit matched to the fastener head to avoid cam-out and fastener damage. Apply consistent, steady pressure when driving to allow the drill point to engage before thread engagement begins. Do not overdrive — stop driving when the washer head seats flush against the substrate to avoid stripping the threads or deforming the material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 12-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 14 threads per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Size\u003c\/strong\u003e: No. 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: ITW BUILDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 560039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITW BUILDEX","offers":[{"title":"Default Title","offer_id":51697828135218,"sku":"560039","price":92.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7ce7a6c2ab3fff4bb5c88c579cb47dd_7af4c6da-afa0-4bab-a609-2a3111ca8ce0.jpg?v=1788354700","url":"https:\/\/voomisupply.com\/products\/itw-buildex-560039-self-drilling-screw-12-hex-washer-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
