Constructed from 1016\/1024 grade steel with a zinc-plated finish for corrosion resistance, this fastener features a number 3 drill point that cuts its own mating thread on contact. The hex drive head accepts a standard hex driver or nut driver, making installation fast in production or field service environments. Licensed electricians, HVAC installers, and sheet metal mechanics routinely use self drilling screws of this type when securing ductwork, panels, enclosures, and equipment housings.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light-gauge sheet metal assembly, HVAC duct fabrication, electrical enclosure installation, and general trade construction where a self-starting fastener is required. The 1-inch length under head and hex washer head bearing surface distribute clamping load across a wider area than pan or flat head alternatives, reducing the chance of pull-through in thinner gauge material. Minimum order quantity is 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNumber 3 drill point drills and taps in a single operation — no pilot hole required\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex washer head provides a wide bearing surface and accepts standard hex drivers\u003c\/li\u003e\n  \u003cli\u003e1016\/1024 grade steel construction meets AISI, ASME B18.6.3, and SAE J78 standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish adds corrosion resistance for interior and protected exterior applications\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head suits light- to medium-gauge sheet metal fastening\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; sold in multiples of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-inch hex washer head self drilling screw for use in light-gauge sheet metal, HVAC ductwork, electrical enclosures, and similar applications where an ASME B18.6.3 and SAE J78 compliant fastener is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSelf drilling screws of this type are installed by HVAC sheet metal workers, electricians, and general trade mechanics using a hex-drive or nut-driver bit at controlled speed to prevent overdriving. Power down or de-energize any panel or enclosure before fastening near live components. Avoid applying excessive torque that could strip the self-tapped thread or distort thin gauge material. Follow applicable codes including SMACNA duct construction standards and NEC requirements for enclosure integrity where relevant.\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\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: Number 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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\u003eMeasurement System\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10 pieces\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: R52001122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711282381106,"sku":"R52001122","price":1199.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fab0d49d495ff0dd4d7d6663539de895.jpg?v=1788475292","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001122-self-drilling-screw-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
