The No. 3 drill point bores through the substrate and threads in a single operation, reducing labor time on the job. The hex washer head distributes clamping load evenly and resists pull-through, while the hex drive accepts standard hex bit drivers for high-torque installation. Constructed from steel with a zinc-plated finish, the screw resists corrosion in typical indoor and sheltered outdoor applications. Length under head measures 3\/4 inch.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in light-gauge metal-to-metal and metal-to-substrate fastening in HVAC ductwork fabrication, sheet metal enclosures, equipment panels, and general trade assembly. The No. 3 drill point is rated for thicker gauge material than a No. 2 point, making it appropriate for structural sheet metal connections where a standard tip would walk or fail to penetrate cleanly. HVAC installers, sheet metal workers, and general contractors typically deploy this fastener in high-volume production or field assembly scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 3 drill point self-taps through material without a pilot hole, saving installation steps\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides broad bearing surface and resists pull-through\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 5\/16-inch hex bit drivers commonly used in trade applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance in sheltered environments\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length under head suits light- to medium-gauge sheet metal connections\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 light- to medium-gauge sheet metal fastening applications typical in HVAC, electrical enclosure, and general sheet metal fabrication work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by sheet metal workers, HVAC technicians, or electricians using a hex-drive bit and an electric screwdriver or impact driver set to an appropriate clutch setting to avoid overdriving. Ensure the workpiece is clamped or secured before driving to prevent movement that can cause the drill point to wander. Do not overdrive — the hex washer head should seat flush against the substrate without deforming the material. Follow applicable codes such as SMACNA standards for ductwork fastener spacing when used in HVAC duct assembly.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1000\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: C29868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696478322994,"sku":"C29868","price":103.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/614e4e79aec1ad1f8304da2fef9d66a9.jpg?v=1788343130","url":"https:\/\/voomisupply.com\/products\/value-collection-c29868-no-12-self-drilling-screw-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
