The 3\/4 inch length under head and No. 3 drill point allow this fastener to penetrate and tap its own mating thread in a single operation, eliminating the need for a pre-drilled pilot hole. The hex washer head provides a built-in bearing surface that distributes clamping load and resists pull-through. Grade 410 stainless steel delivers corrosion resistance suitable for outdoor and corrosive-environment applications. Licensed tradespeople and experienced installers working in HVAC, electrical, and general sheet metal fabrication will find this screw well suited for light-gauge metal-to-metal fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis screw is intended for use in light-gauge sheet metal assemblies where a self-starting, self-tapping fastener is required. Typical applications include HVAC ductwork, electrical enclosures, metal framing, and roofing or cladding installations where stainless steel corrosion resistance is a specification requirement. The hex drive accepts a standard 5\/16 inch hex driver bit or nut driver, making installation fast with a power drill or impact driver. This part is sold in minimum order quantities of 1,000 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 3 drill point self-drills through light-gauge metal without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eGrade 410 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides an integrated seating flange to distribute clamping load\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 5\/16 inch nut driver or hex bit for power tool installation\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch length under head suits typical light-gauge sheet metal fastening applications\u003c\/li\u003e\n  \u003cli\u003eNo. 12 screw size balances holding strength with reduced material distortion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for light-gauge metal assemblies requiring a No. 12 self drilling screw with hex washer head in Grade 410 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16 inch hex nut driver or bit driven by a corded or cordless drill at moderate speed to allow the drill point to engage cleanly without cam-out or tip breakage. Ensure the workpiece is secured before driving to prevent material movement. When fastening dissimilar metals, consult applicable galvanic compatibility guidelines to avoid accelerated corrosion at the joint. De-energize any electrical equipment and follow lockout\/tagout procedures before fastening near live components.\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: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 410\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: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: STHCR1230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694354891058,"sku":"STHCR1230","price":289.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_d526a328-7eec-4bd2-868e-487bf47e6f1d.jpg?v=1788323531","url":"https:\/\/voomisupply.com\/products\/value-collection-sthcr1230-no-12-self-drilling-screw-3-4in","provider":"Voomi Supply","version":"1.0","type":"link"}
