The serrated flange face bites into the mating surface as the fastener is tightened, distributing clamp load across the 0.56-inch flange diameter while resisting loosening from vibration or dynamic loads. The bolt is fully threaded to 1\/4-20 UNC over a 1-inch length under head, made from Grade 5 steel, and finished in zinc yellow dichromate for corrosion protection. These are sold in a pack of 50 and conform to ASME B18.6.3 and SAE J429 standards. Licensed mechanics, millwrights, maintenance technicians, and general contractors commonly install this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for light-duty to medium-duty fastening applications in sheet metal, machinery frames, HVAC equipment enclosures, electrical panels, and general fabrication assemblies. The 1\/4-20 UNC thread is one of the most common unified coarse thread sizes in inch-standard applications, making this bolt a frequently stocked replacement or new-construction fastener for maintenance and repair operations. The serrated flange eliminates the need for a separate lock washer in most applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC fully threaded, 1-inch length under head for maximum thread engagement in thin materials\u003c\/li\u003e\n  \u003cli\u003eSerrated flange diameter of 0.56 inches distributes clamp load and resists loosening under vibration\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 in indoor and light-exposure environments\u003c\/li\u003e\n  \u003cli\u003eHex drive for standard socket or wrench installation\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J429 standards\u003c\/li\u003e\n  \u003cli\u003ePack of 50 for shop stock, maintenance kits, or production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC serrated flange bolt suitable for use wherever a 1\/4-20 inch-series fastener with an integrated locking flange is required in equipment manufacturing, HVAC enclosures, or general mechanical assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex socket or open-end wrench sized for the hex drive. Ensure the mating surface is clean and free of debris so the serrated flange can seat properly and provide its locking function. Power down or de-energize any equipment before installing fasteners on live assemblies. Do not reuse serrated flange bolts in critical joints after removal, as the serrations may not re-engage the mating surface with the same effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: 0.56 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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: KP60860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700091158834,"sku":"KP60860","price":17.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5838086abd0709ae6a9c1e9f3cbb2468.jpg?v=1788385902","url":"https:\/\/voomisupply.com\/products\/value-collection-kp60860-serrated-flange-bolt-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
