It features a No. 4 drill point that cuts through steel and other materials cleanly. The 7\/8-inch length under head suits thin-gauge to medium-gauge substrate applications. Sold in a 100-piece package, this screw is a standard production and service quantity for trade use. It carries a No. 12-24 thread specification, making it compatible with common power driver tooling used in HVAC, sheet metal, and light structural work.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for metal-to-metal and metal-to-substrate fastening in commercial and residential construction, HVAC duct assembly, electrical enclosure work, and light structural panel attachment. The hex washer head provides a broad bearing surface that resists pull-through in thin sheet metal. The hex drive accepts standard 5\/16-inch hex driver bits used across most trade disciplines. The 100-piece package quantity supports jobsite production work and service stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 4 drill point for self-tapping entry into steel without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eNo. 12-24 thread size for strong thread engagement in metal substrates\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides wide bearing surface and reduces pull-through risk\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 5\/16-inch hex driver bits\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch length under head suits thin to medium sheet metal applications\u003c\/li\u003e\n  \u003cli\u003e100-piece package quantity supports production and service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard No. 12 self drilling fastener for use in HVAC ductwork, electrical enclosures, sheet metal fabrication, and light structural panel applications where a No. 4 drill point and hex washer head configuration are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a power driver fitted with a 5\/16-inch hex bit at appropriate speed to avoid stripping or overdriving the hex washer head. Verify substrate thickness matches the drill point rating before driving to ensure full thread engagement. Follow applicable building codes and manufacturer torque guidance for the specific substrate material. Avoid applying excessive lateral force during driving, which can deflect the drill point and reduce holding strength.\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. 12-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 24 threads per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Size\u003c\/strong\u003e: No. 4\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: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 1.03 pounds\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: 560042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITW BUILDEX","offers":[{"title":"Default Title","offer_id":51695046590770,"sku":"560042","price":72.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fdb8db45c45640f4669ca9e8f169584f.jpg?v=1788330812","url":"https:\/\/voomisupply.com\/products\/itw-buildex-560042-self-drilling-screw-no-12-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
