The screw features a hex washer head with a hex drive and a No. 3 drill point that cuts its own pilot hole, eliminating the need for pre-drilling in many light-gauge steel installations. Manufactured from grade 1016\/1024 steel with a zinc-plated finish, it delivers reliable corrosion resistance in standard indoor applications. The length under head measures 4 inches. Weight is 0.8 pounds per package.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in light commercial and residential trade applications including HVAC ductwork assembly, electrical enclosure mounting, metal framing, and sheet metal fabrication. The hex washer head provides a broad bearing surface that resists pull-through, and the hex drive accepts standard 5\/16-inch hex-head driver bits used throughout the trades. The No. 3 drill point is rated for moderate-gauge steel typical of HVAC and light structural work. Minimum order quantity is 25 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 3 drill point self-starts in light- to moderate-gauge steel without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides wide bearing surface and pull-through resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 5\/16-inch power driver bits\u003c\/li\u003e\n  \u003cli\u003eGrade 1016\/1024 steel construction for consistent shear and tensile strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in standard indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets AISI 1016, ASME B18.6.3, and SAE J78 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard No. 12 hex washer head self-drilling screw suitable for light-gauge steel sheet metal fastening typical of HVAC duct systems, metal framing, and electrical enclosure assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a power drill or impact driver fitted with a 5\/16-inch hex bit. Ensure the workpiece is securely clamped or supported before driving to prevent movement that can break the drill point. Do not overdrive — stop once the washer head seats flush against the substrate. Follow applicable SMACNA, NEC, or project specifications for fastener spacing and material gauge ratings.\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\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1016\/1024\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 1016, ASME B18.6.3, SAE J78\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161528\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R52001021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694578106674,"sku":"R52001021","price":1540.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/055271515384228fb7a766f2cccd012f.jpg?v=1788325713","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001021-no-12-self-drilling-screw-4in","provider":"Voomi Supply","version":"1.0","type":"link"}
