Measuring 0.5 inches in diameter with a 3-inch inside width and 5.5-inch leg length, this U-bolt provides a secure mechanical connection to pipe, wood, or structural material. The zinc plating offers basic corrosion resistance for both indoor and light outdoor environments. Each unit ships with a mounting plate and hex nuts included, making it ready for immediate installation without sourcing additional hardware.\u003c\/p\u003e\u003cp\u003eThis U-bolt is suited for plumbing pipe support, automotive component mounting, and general-purpose fastening tasks in residential and light commercial applications. Plumbers and mechanical tradespeople commonly use round U-bolts of this type for suspending pipe runs from joists or structural framing. The included hardware reduces parts sourcing time on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZinc plating provides corrosion resistance for indoor and light-duty outdoor use\u003c\/li\u003e\n\u003cli\u003eRound bend profile suits standard pipe OD fastening applications\u003c\/li\u003e\n\u003cli\u003ePlate and hex nuts included — no additional hardware required\u003c\/li\u003e\n\u003cli\u003eSold individually (each)\u003c\/li\u003e\n\u003cli\u003eCompatible with pipe, wood, and other structural substrates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose round U-bolt suitable for pipe support, automotive, and structural fastening applications in residential and light commercial installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by plumbers, pipefitters, or general mechanical tradespeople. Before fastening, ensure the mounting substrate can support the intended load. Thread hex nuts evenly on both legs to avoid cocking the bolt and apply even clamping force. Verify that pipe support spacing complies with applicable plumbing codes such as the IPC for the pipe material and diameter being supported.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Width\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeg Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.821 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N347-807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51346886164786,"sku":"N347-807","price":16.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550628.jpg?v=1782093563","url":"https:\/\/voomisupply.com\/products\/national-marker-n347-807-zinc-round-u-bolt","provider":"Voomi Supply","version":"1.0","type":"link"}
