Built to Grade 8 steel with a zinc-plated finish, this bolt delivers the clamping strength and corrosion resistance required in demanding trade applications. The integrated serrated flange distributes load across a 0.68-inch flange diameter and bites into mating surfaces to resist loosening under vibration — eliminating the need for a separate washer. The hex drive head allows standard socket or wrench installation. Mechanical contractors, HVAC technicians, electricians, and equipment fabricators install this type of fastener wherever a high-strength, vibration-resistant connection is required.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light commercial and industrial equipment assembly, HVAC unit mounting, electrical enclosure fabrication, and general mechanical service work. The 5\/16-18 UNC thread pattern and 1-1\/4-inch length under head make it a common choice for panel mounting, bracket attachment, and equipment frame assembly where vibration loosening is a concern. It is sold individually but requires a minimum order quantity of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eSerrated flange bites into mating surface to resist vibration loosening without a separate washer\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and protected outdoor applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the 1-1\/4-inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and open-end wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J429 standards for dimensional and mechanical consistency\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 a Grade 8 fully threaded 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 requires a hex socket or open-end wrench sized for a 5\/16-inch hex drive. Ensure mating threads are clean and free of debris before installation. The serrated flange requires firm, consistent torque to properly seat against the clamping surface — do not use with hardened washers or plates that would prevent the serrations from engaging. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.\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: 1-1\/4 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 8\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: 0.039 pounds\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: 825334MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695803105586,"sku":"825334MSC","price":6446.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e66739ec2322dab7633c78ab22baff21.jpg?v=1788338359","url":"https:\/\/voomisupply.com\/products\/value-collection-825334msc-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
