It features a 5\/16-inch hex washer head driven by a hex drive tool, eliminating the need for a pre-drilled pilot hole. The number 3 drill point cuts through material cleanly on contact. Made from grade 1016-1024 steel with a zinc-plated finish, this screw resists corrosion and meets AISI 1016, ASME B18.6.3, and SAE J78 standards. Electricians, HVAC installers, and sheet metal workers commonly use this fastener when securing duct work, panels, and structural framing components.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light commercial and residential trade applications where a self-tapping, self-drilling fastener is required. The 1-1\/4-inch length under head makes it appropriate for single- or double-layer sheet metal connections. The hex washer head distributes clamping load across a wider bearing surface, reducing the chance of pull-through on thinner gauge material. HVAC sheet metal technicians and general contractors will find this fastener appropriate for duct assembly, metal stud framing, roofing panels, and similar structural or enclosure work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNumber 3 drill point self-drills without a pilot hole, speeding up installation\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex washer head provides a wide bearing surface to resist pull-through\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard hex bit drivers and nut drivers\u003c\/li\u003e\n  \u003cli\u003eGrade 1016-1024 steel construction for reliable shear and tensile strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in typical indoor and sheltered applications\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 self drilling fastener for use in sheet metal, light-gauge steel framing, and similar trade applications where a 5\/16-inch hex washer head screw with a number 3 drill point is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex drive bit or nut driver sized for a 5\/16-inch head. Apply steady, consistent pressure to allow the drill point to engage the material before the threads advance. Do not over-torque, as stripping the fastener or distorting thin sheet metal is possible with power tools set at high clutch settings. Follow applicable building codes and manufacturer specifications for fastener spacing and load requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\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\u003eDrill Point Size\u003c\/strong\u003e: 3\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\u003eWeight\u003c\/strong\u003e: 0.29 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: 10\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: 3120KW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690586538290,"sku":"3120KW","price":727.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/205679eaa97ad0fa70a82a4953e31238.jpg?v=1788272169","url":"https:\/\/voomisupply.com\/products\/value-collection-3120kw-self-drilling-screw-5-16-in-hex-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
