Fabricated from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in exposed or damp installation environments. The 1\/2-13 UNC thread size provides a reliable, high-strength connection, and the 1-1\/2-inch thread length gives adequate engagement with standard hex nuts. Two nuts are included. With a finished length of 6 inches and a width of 4-1\/2 inches, this U-bolt fits standard 4-inch pipe schedules and is installed by licensed plumbers, pipefitters, and mechanical contractors during pipe support and suspension work.\u003c\/p\u003e\u003cp\u003eThis U-bolt is suited for residential and commercial pipe support applications involving 4-inch pipe runs. Common use cases include securing horizontal or vertical pipe segments to structural members, equipment bases, or unistrut channel. The mount plate style simplifies attachment to flat surfaces without requiring a separate clamp back. It is commonly used in HVAC hydronic piping, fire protection rough-in, plumbing drain and waste lines, and general mechanical piping installations where a galvanized finish is specified for corrosion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot galvanized finish provides corrosion resistance in wet or exposed environments\u003c\/li\u003e\n\u003cli\u003eC-1010 steel construction delivers reliable mechanical strength for pipe support loads\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread with 1-1\/2-inch thread length for secure nut engagement\u003c\/li\u003e\n\u003cli\u003eMount plate style allows direct attachment to flat structural surfaces\u003c\/li\u003e\n\u003cli\u003eSized for 4-inch pipe with a 4-1\/2-inch width and 6-inch overall length\u003c\/li\u003e\n\u003cli\u003eIncludes two hex nuts for complete, ready-to-install assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pipe support fastener for standard 4-inch pipe in mechanical, plumbing, and HVAC piping systems using inch-standard hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or mechanical contractors in accordance with applicable plumbing and mechanical codes. Power down or shut off the relevant system before disturbing any existing pipe supports. Ensure the mounting surface or structural member is rated to carry the pipe load before fastening. Do not overtighten the nuts in a way that distorts the pipe wall; tighten to snug plus the appropriate turns per standard fastening practice for the pipe material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: With Mount Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Pipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: C-1010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2 Hex Nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.93 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GIB53713\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51715671195954,"sku":"GIB53713","price":34.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07c09380d766bd81bdd3a335dfc14865_1f033dd6-57da-4454-a3fc-049e0fdeafe6.jpg?v=1788517015","url":"https:\/\/voomisupply.com\/products\/gibraltar-gib53713-round-u-bolt-4-inch-pipe-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
