Sized at 3\/8 inch diameter with a 3-inch inside width and 7-inch leg length, this U-bolt is designed to secure pipe, conduit, tubing, or other cylindrical and rectangular stock to wood or metal framing members. The 657-series zinc finish provides corrosion resistance suitable for interior and protected exterior environments. Each package contains 5 fasteners, sold as a boxed loose unit pack.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is commonly used by plumbers, electricians, HVAC technicians, and general contractors when anchoring runs of pipe or conduit to structural members, equipment frames, or support channels. The square-bend geometry conforms to rectangular tubing and lumber profiles, providing a stable, low-rattle hold. At 2.34 pounds per 5-pack, these are a practical stocking item for service vans and supply rooms. The included plate and hex nuts eliminate the need for sourcing separate hardware before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare-bend profile fits rectangular wood and metal objects securely\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides corrosion resistance for indoor and protected outdoor use\u003c\/li\u003e\n  \u003cli\u003ePlate and hex nuts included — no additional hardware required\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch diameter rod stock for solid clamping strength\u003c\/li\u003e\n  \u003cli\u003ePackaged 5 per box for convenient stocking and job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for securing pipe, conduit, tubing, and similar cylindrical or rectangular objects to wood and metal structural members in general mechanical, plumbing, and electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by plumbers, electricians, or HVAC technicians following applicable code requirements such as the NEC or IPC for support spacing. Ensure the mounting surface is structurally sound before fastening. Snug hex nuts evenly on both sides of the plate to avoid canting the U-bolt under load. Do not overtighten on plastic or thin-wall conduit, as the square-bend profile concentrates clamping force along the contact edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 3\/8 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: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc (657 series)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBend Style\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Included\u003c\/strong\u003e: Plate and hex nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N222-372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51557771346226,"sku":"N222-372","price":31.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79106b6efbc34b30206067b709d2be4c.jpg?v=1786394797","url":"https:\/\/voomisupply.com\/products\/national-mfg-n222-372-square-u-bolt-3-8x3x7-zinc-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
