The integrated serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. The bolt features a 3\/8-16 UNC thread, a 2-inch length under head, and is fully threaded from head to tip. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. This SKU ships in a package quantity of 50.\u003c\/p\u003e\u003cp\u003eSerrated flange bolts in this size range are widely used in HVAC equipment assembly, electrical enclosure mounting, light structural fabrication, and general mechanical applications where a separate washer is impractical or undesirable. The 3\/8-16 UNC thread is a common size across commercial and residential equipment panels, brackets, and frames. Grade 5 steel provides sufficient tensile strength for most medium-duty fastening applications encountered by HVAC technicians, electricians, and mechanical contractors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSerrated flange distributes load and resists loosening under vibration without a separate washer\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread, fully threaded for maximum engagement flexibility\u003c\/li\u003e\n\u003cli\u003e2-inch length under head suits medium-depth through-bolting applications\u003c\/li\u003e\n\u003cli\u003eGrade 5 steel construction meets SAE J429 tensile strength requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance in indoor and sheltered environments\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.6.3 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension 3\/8-16 UNC serrated flange bolt per ASME B18.6.3, suitable for use in any application requiring a hex-drive fully threaded flange bolt in this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a standard hex socket or open-end wrench sized for 3\/8-16 fasteners. Ensure mating threads are clean and free of debris before driving. Do not exceed the torque rating appropriate for Grade 5 steel at this thread diameter as specified by the equipment manufacturer or relevant fastener standards. Zinc-plated fasteners are intended for indoor or sheltered use and should not be substituted for stainless or hot-dip galvanized hardware in corrosive or outdoor-exposure environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: 0.81 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 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\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\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: KP24746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696011280690,"sku":"KP24746","price":74.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b15b46288231e4f88bc6e12320f74658.jpg?v=1788339768","url":"https:\/\/voomisupply.com\/products\/value-collection-kp24746-3-8-16-unc-serrated-flange-bolt-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
