Featuring a hex washer head with a hex drive, this screw provides strong torque transfer and a broad bearing surface that resists pull-through. The 3\/4 inch length under head suits light-gauge metal-to-metal and metal-to-substrate applications common in HVAC duct work, electrical enclosures, and general sheet metal assembly. The 3 point drill tip bites quickly into the work surface, reducing installation time. Constructed from steel with a zinc-plated finish, it provides corrosion resistance suitable for dry indoor applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in residential and light commercial construction and service work. HVAC technicians reach for self drilling screws when securing sheet metal duct sections, attaching flanges, or fastening equipment panels. Electricians use them for mounting enclosures and raceways to metal framing. The hex washer head seats flush against the material surface, making it practical anywhere a clean, stable fastening point is needed on thin metal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch diameter with 3\/4 inch length under head for light-gauge sheet metal fastening\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides a wide bearing surface and resists pull-through\u003c\/li\u003e\n  \u003cli\u003eHex drive for positive bit engagement and high torque transfer\u003c\/li\u003e\n  \u003cli\u003e3 point self drilling tip eliminates the need for a pilot hole\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance in dry indoor environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use fastener for light-gauge metal assemblies in HVAC, electrical, and sheet metal applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex driver bit and a variable-speed drill or impact driver set to a controlled torque to avoid stripping the head or over-driving into thin material. Verify material gauge compatibility with the 3 point drill tip before driving. Power down or de-energize any equipment before fastening near live electrical components. Follow applicable codes such as the NEC and SMACNA standards for fastener spacing in duct and enclosure assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 1\/4 inch\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\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 Point\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161528\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: MP33846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718613434674,"sku":"MP33846","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0b115c988e560f3be361809906bbdd6.jpg?v=1788554570","url":"https:\/\/voomisupply.com\/products\/value-collection-mp33846-self-drilling-screw-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
