The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration and dynamic loading. The bolt measures 2 inches in length under head, is fully threaded along its entire shank, and features a 5\/16-18 UNC thread form. Manufactured from Grade 8 steel with a zinc-plated finish for corrosion resistance, it meets ASME B18.6.3 and SAE J429 standards. Installed by maintenance technicians, millwrights, and trade professionals across industrial, mechanical, and structural assembly work.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for applications where standard hex bolts or flange bolts without serrations may back out over time due to vibration. Common use cases include equipment mounting, bracket fastening, and mechanical assembly in both residential and commercial settings. The fully threaded shank makes it adaptable for through-hole applications at varying grip lengths within its 2-inch range. The zinc-plated finish provides moderate corrosion protection for indoor or mildly humid environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange bearing surface resists loosening under vibration without requiring a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the full 2-inch length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in general-purpose environments\u003c\/li\u003e\n  \u003cli\u003eHex drive for standard socket or wrench installation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J429 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC serrated flange bolt suitable for use in any application requiring an inch-series, coarse-thread Grade 8 fastener with an integrated flange bearing surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex socket or open-end wrench sized for the 5\/16-18 bolt head. Ensure mating threads are clean and free of debris before installation. Torque to the value specified by the equipment manufacturer or applicable fastener standard for Grade 8 fasteners at this thread size. The serrated flange is designed for use against metal bearing surfaces — avoid using against soft or coated materials where the serrations 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\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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: 0.0524 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 825340MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722459513138,"sku":"825340MSC","price":8643.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c74d839b861b0aba45aee7b9556b45a.jpg?v=1788591443","url":"https:\/\/voomisupply.com\/products\/value-collection-825340msc-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
