Built from Grade 2 steel to AISI C1022 standards, it features a serrated flange that bites into the mating surface to resist loosening under vibration. The zinc-plated finish provides basic corrosion resistance for general-purpose fastening applications. The integrated flange eliminates the need for a separate washer and distributes clamping load across a wider bearing area. This fastener is installed by electricians, plumbers, HVAC technicians, and general tradespeople wherever a compact, vibration-resistant bolt connection is required.\u003c\/p\u003e\u003cp\u003eThis flange bolt is suited for light to medium-duty fastening in residential and commercial trade applications. The 1\/4-20 UNC coarse thread engages quickly and holds reliably in steel, aluminum, and other common structural materials. The serrated underside of the flange locks against the workpiece surface without requiring thread-locking compound. It is appropriate for panel mounting, equipment attachment, conduit support, and similar utility fastening tasks encountered across HVAC, plumbing, and electrical trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC coarse thread for fast engagement and broad hardware compatibility\u003c\/li\u003e\n\u003cli\u003eFully threaded shank provides maximum thread engagement across the full 1-inch grip length\u003c\/li\u003e\n\u003cli\u003eSerrated flange resists loosening caused by vibration without additional locking hardware\u003c\/li\u003e\n\u003cli\u003eIntegrated flange distributes load and eliminates the need for a separate flat washer\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction to AISI C1022 standard for general-purpose strength\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for basic corrosion resistance in indoor and sheltered installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 1\/4-20 UNC hex drive flange bolt suitable for standard fastening applications across HVAC, electrical, plumbing, and mechanical trade work wherever a 1\/4-20 coarse-thread serrated flange bolt is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with a hex key or hex bit driver sized for the drive recess. Power down or de-energize any equipment before fastening components near electrical panels or live circuits, in accordance with NEC lockout\/tagout requirements. The serrated flange requires direct metal-to-metal contact to function as a locking element — do not install over paint, gaskets, or soft materials where the serrations cannot engage. Inspect the mating surface for flatness before torquing to ensure even load distribution.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 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\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Drive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 0.513 to 0.531 inches\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: Grade 2 Steel (AISI C1022)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.78 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\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: R52001050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702085484850,"sku":"R52001050","price":4784.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b59e1b4b7ff0a4a706d67a4d288b8386.jpg?v=1788408945","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001050-flange-bolt-1-4-20-unc-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
