Built from C-1010 steel with a zinc-plated finish for corrosion resistance, this fastener uses a 1\/2-13 UNC thread with a 3-inch thread length, providing ample engagement for standard hex nuts. The U-bolt ships without a mount plate, making it suitable for applications where the installer supplies their own backing hardware or mounts directly to a strut or structural member. Four nuts are included. Weight is 0.82 pounds per unit.\u003c\/p\u003e\n\u003cp\u003eThis U-bolt is sized for 3-1\/2 inch pipe and carries a 4-1\/16 inch inside width to clear standard Schedule 40 and Schedule 80 pipe of that nominal diameter. Typical install scenarios include pipe hanger assemblies in mechanical rooms, boiler rooms, plumbing rough-in, and HVAC refrigerant or hydronic piping support runs. Plumbers, pipefitters, and mechanical contractors are the primary installers. The zinc-plated steel construction suits indoor and semi-protected environments where moderate corrosion resistance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread for compatibility with standard hex hardware\u003c\/li\u003e\n  \u003cli\u003e3-inch thread length provides full nut engagement on typical pipe hanger assemblies\u003c\/li\u003e\n  \u003cli\u003e4-1\/16 inch inside width fits 3-1\/2 inch nominal pipe\u003c\/li\u003e\n  \u003cli\u003eC-1010 steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eShips without mount plate for flexible backing configurations\u003c\/li\u003e\n  \u003cli\u003eIncludes four nuts — no additional hardware required for basic installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit U-bolt for 3-1\/2 inch nominal pipe support applications using 1\/2-13 UNC threaded hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, pipefitters, or mechanical contractors following applicable IPC or IFGC support-spacing requirements. Shut off flow and depressurize the line before repositioning any existing pipe hangers. Torque nuts evenly to avoid cocking the U-bolt across the pipe.
