The serrated flange face bites into the mating surface as the fastener is tightened, providing resistance to loosening under vibration without requiring a separate lock washer. Sized at 5\/16-18 UNC with a 2-1\/4 inch length under the head and fully threaded shank, this bolt is manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. It is driven with a standard hex wrench or socket. Installers in HVAC, electrical, plumbing, and general mechanical trades will encounter this fastener in panel, bracket, and equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for residential and light commercial assembly work where vibration-resistant fastening is required without adding separate lock hardware. The fully threaded shank allows engagement along the entire bolt length, making it useful in thin-material and through-bolt configurations. The 0.68 inch flange diameter provides a broader bearing surface than a standard hex bolt head, distributing clamp load over a wider area. It is appropriate for use in equipment enclosures, mounting brackets, ductwork supports, and similar structural attachment points encountered across trade disciplines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange face resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows full engagement in thin-material and through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in standard indoor and light-exposure environments\u003c\/li\u003e\n  \u003cli\u003e0.68 inch flange diameter distributes clamp load over a broader bearing surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standards for hex flange fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC inch-series serrated flange bolt suitable for general mechanical assembly, bracket mounting, and equipment fastening applications where a vibration-resistant hex flange fastener is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized for the hex drive. Ensure the mating surface is clean and free of coatings that would prevent the serrations from seating properly. Do not use with soft materials where the serrated flange may cause surface damage that compromises the joint. Follow applicable torque specifications from the equipment manufacturer or relevant standards when assembling structural or load-bearing connections.\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: 2-1\/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\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\u003eFlange Type\u003c\/strong\u003e: Serrated\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-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: 0.0545 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: 825098MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51752738652466,"sku":"825098MSC","price":9056.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32a68a8ba98a5cf38df18acd65440751.jpg?v=1788930039","url":"https:\/\/voomisupply.com\/products\/value-collection-825098msc-serrated-flange-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
