This bolt features a 1\/4-20 UNC thread at 3\/4 inch length under head, fully threaded along its entire shank. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Manufactured from AISI C1022 steel to Grade 2 specification and finished with zinc plating for corrosion resistance, this bolt is suited for general-purpose use in light industrial, mechanical, and maintenance applications. Licensed tradespeople and maintenance technicians working with sheet metal enclosures, equipment panels, or structural brackets will find this fastener a reliable standard choice.\u003c\/p\u003e\n\u003cp\u003eThis serrated flange bolt is used in applications where vibration resistance and a built-in washer surface are needed without a separate flange washer or lock washer. Common install scenarios include HVAC cabinet assembly, electrical enclosure mounting, equipment frames, and general mechanical assembly work where 1\/4-20 UNC threading is specified. The fully threaded shank allows engagement across the full fastened thickness, making it suitable for thinner material joints. These bolts are sold with a minimum order quantity of 100 units per order and ship as a single package quantity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange face bites into mating surface to resist loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides complete thread engagement across the full grip length\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eGrade 2 AISI C1022 steel construction meets general-purpose structural fastening requirements\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides basic corrosion resistance for indoor and light-duty outdoor use\u003c\/li\u003e\n  \u003cli\u003eHex drive head allows installation with standard hex wrenches or socket drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock fastener for any application requiring a 1\/4-20 UNC serrated flange bolt with 3\/4 inch length under head and fully threaded shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket driver sized to the hex head. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading. Do not overtighten beyond the torque rating appropriate for Grade 2 fasteners at this thread size, as specified by the applicable engineering or maintenance documentation. Zinc-plated fasteners are intended for dry or mildly humid environments and should not be used in contact with dissimilar metals in corrosive conditions without appropriate isolation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.513 to 0.531 inches\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: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: AISI C1022\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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\u003ePackage Weight\u003c\/strong\u003e: 1.49 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 406020PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717311365426,"sku":"406020PR","price":3018.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d93d4fd09a49c2235b49c91355a5abb.jpg?v=1788538312","url":"https:\/\/voomisupply.com\/products\/value-collection-406020pr-serrated-flange-bolt-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
