The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening from vibration. Manufactured from Grade 5 steel with a zinc-plated finish, the bolt measures 1\/2 inch in length under the head and is fully threaded with a 5\/16-18 UNC thread form. A hex drive allows installation with standard wrenches or sockets. Conforms to ASME B18.6.3 and SAE J429 standards.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light-to-medium duty fastening tasks where vibration resistance is required without a separate lock washer. Typical applications include equipment mounting, panel assemblies, HVAC component brackets, electrical enclosures, and general metalwork where a unified inch thread is specified. The zinc plating provides baseline corrosion resistance for indoor and protected outdoor environments. Installers working to UNC thread specifications will find this bolt a direct-fit option in most standard 5\/16-18 tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange provides built-in vibration resistance without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC for maximum thread engagement in short-grip applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in dry or protected environments\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard wrenches and sockets\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 replacement or stocking fastener for any application requiring a 5\/16-18 UNC fully threaded serrated flange bolt with 1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians, millwrights, or trade professionals using a standard hex wrench or socket driver. Always ensure the mating tapped hole or nut is clean and free of debris before threading. Do not exceed the torque range appropriate for Grade 5 fasteners of this thread size as specified in the applicable engineering standard. The serrated flange is intended for use against metal mating surfaces; avoid installation against soft or coated surfaces where serration may cause damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 0.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\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: 0.026 pounds\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: 825084MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696684400946,"sku":"825084MSC","price":3226.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd9301c84138552c712de2c7ffe24795.jpg?v=1788345194","url":"https:\/\/voomisupply.com\/products\/value-collection-825084msc-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
