The serrated flange acts as an integrated locking washer, biting into the mating surface to resist loosening from vibration and torque. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt meets ASME B18.6.3 and SAE J429 standards. Thread size is 1\/4-20 UNC with a 2-1\/4 inch length under head and a 0.56 inch flange diameter. Installed with a standard hex drive, it is suited for HVAC panels, equipment enclosures, and light structural applications.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for residential and commercial mechanical applications where a vibration-resistant fastener is needed without a separate lock washer. Common install scenarios include securing HVAC sheet metal components, electrical enclosures, motor mounts, and general equipment assembly. The fully threaded shank provides maximum thread engagement across the entire length under head, making it effective in thin-material and through-hole applications. Tradespeople in HVAC, electrical, and general mechanical service will find this fastener compatible with standard 1\/4-20 tapped holes and clearance hole layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange provides built-in locking action, eliminating the need for a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement through the entire 2-1\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and sheltered outdoor use\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and wrenches\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC inch-series serrated flange bolt suitable for use in any application requiring a 1\/4-20 tapped hole or clearance hole per ASME B18.6.3 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized for a 1\/4-20 UNC flange bolt. Ensure the mating surface is clean and free of debris so the serrated flange seats fully and provides proper locking engagement. Do not use an additional lock washer with a serrated flange bolt, as stacking locking elements can reduce clamp load consistency. Follow applicable torque guidelines from the relevant equipment manufacturer or industry fastener standards for Grade 5 hardware.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 5\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: ASME B18.6.3, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0316 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 825068MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689714385202,"sku":"825068MSC","price":5524.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c869b3b0c980e026ebd043042bd68e2.jpg?v=1788263342","url":"https:\/\/voomisupply.com\/products\/value-collection-825068msc-serrated-flange-bolt-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
