The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut accepts a 5\/16-18 UNC thread and features a 13\/16-inch flange diameter with a flange height of 0.283 inches. Sold in a package of 100, it suits high-volume trade applications in HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and general mechanical fabrication.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for light to medium-duty applications where a standard hex nut with an integrated locking flange is required. The serrated bearing surface makes it well-suited for use on sheet metal, brackets, and equipment enclosures where vibration is a concern. The zinc-plated finish provides adequate protection in dry indoor environments. Installers in HVAC, electrical, and general mechanical trades commonly use this nut when assembling equipment frames, mounting components, or securing cover panels requiring a reliable, self-locking connection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSerrated flange locks against mating surface to resist loosening under vibration\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread size for compatibility with standard fractional fastener hardware\u003c\/li\u003e\n\u003cli\u003e13\/16-inch flange diameter distributes clamping load over a wider bearing area\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction provides adequate strength for light to medium-duty applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers basic corrosion resistance in dry indoor environments\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 100 for efficient use in production and service work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5\/16-18 UNC threaded fasteners and bolts in standard inch-measurement assemblies.

Ensure mating threads are clean and free of debris before installation. Apply torque evenly and do not exceed the rated capacity for Grade 2 fasteners at this thread size. The serrated flange is designed for use on bare metal or lightly coated surfaces — avoid installing over thick paint or non-metallic materials where the serrations cannot seat properly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Serrated Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 13\/16 inches (0.8025 inches minimum, 0.8125 inches maximum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 0.283 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Width Across Flats\u003c\/strong\u003e: 0.489 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Width Across Flats\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Height\u003c\/strong\u003e: 0.268 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Height\u003c\/strong\u003e: 0.283 inches\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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C86314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703974887730,"sku":"C86314","price":39.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cee8f6fd5cb98ab99c426048926701fc.jpg?v=1788419805","url":"https:\/\/voomisupply.com\/products\/value-collection-c86314-serrated-flange-nut-5-16-18-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
