The No. 3 drill point bores through light-gauge steel and similar substrates in a single operation. Built from steel with a zinc-plated finish for corrosion resistance, this screw measures 3\/4 inches in length under the head. It is a standard inch-measurement fastener suited for metalwork, light fabrication, HVAC ductwork, and general trade assembly applications.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications where speed and repeatability matter. The hex washer head provides a built-in bearing surface that distributes clamping load, while the hex drive allows use with standard nut drivers and hex-bit power tools. Typical install scenarios include securing sheet metal panels, attaching HVAC duct components, light structural bracketing, and general mechanical assembly where a self-tapping, self-drilling fastener is specified. Sold with a minimum order quantity of 25 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 3 drill point self-drills through light-gauge steel without a pilot hole\u003c\/li\u003e\n\u003cli\u003eHex washer head provides integrated bearing surface for consistent clamping\u003c\/li\u003e\n\u003cli\u003eHex drive is compatible with standard nut drivers and hex-bit power tools\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction offers basic corrosion resistance for general indoor use\u003c\/li\u003e\n\u003cli\u003e3\/4 inch length under head suits thin-material fastening tasks\u003c\/li\u003e\n\u003cli\u003eInch-standard sizing for straightforward replacement and cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose No. 12 self-drilling fastener for use in light-gauge steel, sheet metal, and similar thin-material applications common in HVAC, electrical, and mechanical trade work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, sheet metal workers, electricians, or general mechanical trades using a hex-bit driver or nut driver at appropriate speed for the substrate. Ensure the workpiece is secured before driving to prevent material walking. Do not overdrive — the hex washer head seat indicates proper torque has been reached. Follow applicable codes and manufacturer guidelines for fastener spacing and edge distance in structural or load-bearing assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 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\u003eMeasurement System\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: 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MP33838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696853221682,"sku":"MP33838","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f451e7ae6256a75fedefd5e13c049930.jpg?v=1788347055","url":"https:\/\/voomisupply.com\/products\/value-collection-mp33838-self-drilling-screw-no-12","provider":"Voomi Supply","version":"1.0","type":"link"}
