It features a 3\/8-16 UNC thread size with a 1.5-inch thread length and a 4.17-inch inside width. Constructed from 304 stainless steel, it delivers corrosion resistance suited to wet, outdoor, or chemically active environments. The hardware includes two serrated flange nuts, which provide secure clamping without requiring separate flat washers. Plumbers, pipefitters, HVAC technicians, and general mechanical contractors use this fastener to anchor pipe runs to structural supports in both commercial and residential installations.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is intended for use with 4-inch nominal pipe and mounts via a clamping configuration against a flat or structural surface. The inch-measurement thread system and standard UNC thread form make it compatible with common hand tools and hardware found on most job sites. It is well suited for pipe support work in mechanical rooms, utility corridors, rooftop equipment installations, and anywhere corrosion-resistant hardware is specified. The included serrated flange nuts eliminate the need to source separate fasteners, keeping installation straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction provides corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread size with 1.5-inch thread length for secure clamping engagement\u003c\/li\u003e\n  \u003cli\u003e4.17-inch inside width fits 4-inch nominal pipe\u003c\/li\u003e\n  \u003cli\u003eIncludes two serrated flange nuts for a complete, ready-to-install fastener assembly\u003c\/li\u003e\n  \u003cli\u003eClamping mount style seats against flat structural surfaces without welding or special brackets\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard UNC thread form for compatibility with common trade tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style clamping support fastener for 4-inch nominal pipe applications in plumbing, HVAC, and mechanical piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or mechanical contractor in accordance with applicable IPC or IFGC support spacing requirements. Shut off flow and depressurize the pipe before repositioning any existing clamps or supports. Use a properly sized wrench to tighten the included serrated flange nuts evenly on both legs of the U-bolt to prevent cocking or uneven clamping load. Do not over-torque stainless steel hardware, as galling can occur without proper lubrication.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Pipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Width\u003c\/strong\u003e: 4.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 \/ Grade 2 Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2 Serrated Flange Nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.82 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: U400KSS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68387463823666,"sku":"U400KSS","price":28.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68a69c6b3b6f0db6af52150a2d8e8b40.jpg?v=1793903916","url":"https:\/\/voomisupply.com\/products\/value-collection-u400kss-round-u-bolt-4-in-pipe-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
