The serrated flange face bites into the mating surface as the bolt is tightened, distributing clamp load across a wider area while resisting loosening from vibration or dynamic loads. Thread size is 5\/16-18 UNC with a fully threaded shank, 1-1\/2 inches length under head, and a flange diameter of 0.68 inches. The bolt is manufactured from Grade 5 steel and finished with a zinc yellow dichromate coating for corrosion resistance. Electricians, HVAC technicians, plumbers, and general mechanical contractors install these in panel assemblies, brackets, equipment frames, and conduit support structures.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light- to medium-duty fastening applications in both residential and commercial environments. The fully threaded 5\/16-18 UNC configuration allows engagement along the entire shank length, making it effective in thin material applications and short-depth blind holes. The serrated flange eliminates the need for a separate lock washer in most standard installations. Sold in packages of 50, making it appropriate for production assembly, service van stocking, or job-site use where multiple fasteners of this size are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange face provides vibration resistance without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC shank for maximum thread engagement across the full 1-1\/2 inch length\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance for general indoor and light outdoor use\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 0.68 inches distributes clamping load over a wider bearing surface\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 5\/16-18 UNC serrated flange bolt suitable for use in any application calling for a hex-drive, fully threaded flange bolt of this thread size and length under head per ASME B18.6.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex socket or open-end wrench sized for a 5\/16-18 UNC hex flange bolt head. Power down or de-energize any electrical equipment before fastening components in or near live panels. Ensure mating threads are clean and free of debris before installation. Do not over-torque, as the serrated flange can deform thin sheet metal substrates if excessive force is applied.\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: 1-1\/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\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: 0.68 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: KP24737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716121493810,"sku":"KP24737","price":29.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5657ee83cd55009b5c3b5bb9c94457a3.jpg?v=1788522025","url":"https:\/\/voomisupply.com\/products\/value-collection-kp24737-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
