Built to Grade 8 steel with a zinc-plated finish, it delivers high tensile strength and corrosion resistance in demanding applications. The integrated serrated flange distributes clamping load over a wider surface area and bites into the mating material to resist loosening under vibration. Thread size is 3\/8-16 UNC with a 3\/4 inch length under head, fully threaded from tip to flange. The flange diameter measures 0.81 inches. Drive type is hex. This bolt conforms to ASME B18.6.3 and SAE J429 standards.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general industrial, automotive, and equipment assembly applications where a standard hex bolt with a built-in flange washer is preferred. The serrated underside of the flange locks against the mating surface without requiring a separate lock washer, making it practical in production and field repair scenarios. Typical users include assembly technicians, maintenance mechanics, and fabricators working with steel and heavy equipment structures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eSerrated flange resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in standard indoor and light outdoor environments\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-16 UNC shank, 3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 0.81 inches spreads clamping load over a larger bearing area\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 3\/8-16 UNC serrated flange bolt suitable for use in any application requiring a Grade 8 hex flange fastener conforming to ASME B18.6.3 and SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket. Ensure mating threads are clean and free of debris before driving the bolt. Do not exceed the torque rating appropriate for Grade 8, 3\/8-16 UNC fasteners as specified in the applicable engineering reference or equipment service manual. The serrated flange requires firm, flat seating against the mating surface to function correctly — avoid use on soft or coated surfaces where serrations may not engage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 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\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\u003eFlange Diameter\u003c\/strong\u003e: 0.81 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 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: 0.0475 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: 825346MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696919511346,"sku":"825346MSC","price":7090.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9864939ac4f084a9dd97fa22ff5f30.jpg?v=1788347649","url":"https:\/\/voomisupply.com\/products\/value-collection-825346msc-serrated-flange-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
