Manufactured from C-1010 steel with a hot galvanized finish, it resists corrosion in wet and outdoor installations. The 5\/16-18 UNC thread is 1 inch long and includes two nuts for immediate assembly. At 0.18 pounds, this lightweight fastener is sized for trade professionals installing pipe supports in plumbing, HVAC, and mechanical systems where a clean, plate-free attachment is required.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is used in residential and commercial mechanical applications where 2-1\/2 inch pipe must be anchored to unistrut, threaded rod hangers, structural steel, or wood framing. It is commonly installed by plumbers, pipefitters, and HVAC technicians during new construction and retrofit work. The hot galvanized finish makes it suitable for damp locations, outdoor runs, and corrosive environments where bare steel fasteners would degrade prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound bend profile sized for 2-1\/2 inch pipe outside diameter\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard with 1 inch thread length\u003c\/li\u003e\n  \u003cli\u003eHot galvanized finish for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eC-1010 steel construction for reliable mechanical strength\u003c\/li\u003e\n  \u003cli\u003eShips with two hex nuts included — no additional hardware required for basic installation\u003c\/li\u003e\n  \u003cli\u003eNo mount plate design allows direct attachment to channel, rod, or flat surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard trade fastener for pipe support systems requiring a 5\/16-18 UNC round U-bolt on 2-1\/2 inch nominal pipe.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or mechanical contractors following applicable IPC and IFGC pipe support spacing requirements. Shut off and depressurize the pipe line before repositioning or replacing existing supports. Hand-tighten the included nuts evenly on both legs before applying final torque to avoid cocking the bolt and distorting the pipe. Do not over-tighten on plastic-lined or thin-wall pipe — verify the pipe material and wall thickness before applying clamping force.\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\u003eFor Pipe Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3-11\/16 inches\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\u003eMount Type\u003c\/strong\u003e: Without Mount Plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2 Nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GIB53071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722790895922,"sku":"GIB53071","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c10e06514ad0b24cbde6dba90aa5d165.jpg?v=1788595960","url":"https:\/\/voomisupply.com\/products\/gibraltar-gib53071-round-u-bolt-5-16-18-unc-2-1-2-inch-pipe","provider":"Voomi Supply","version":"1.0","type":"link"}
