Constructed from C-1010 steel with a hot galvanized finish, it resists corrosion in exposed or outdoor installations. The 5\/16-18 UNC threaded legs provide a standard, widely compatible fastening interface, with a 3 inch thread length giving adequate adjustment range for mounting through strut, unistrut channel, or structural members. The U-bolt measures 4-3\/4 inches in length and 2 inches in width. Two nuts are included. This hardware is installed by plumbers, pipefitters, HVAC technicians, and mechanical contractors during pipe support and restraint work.\u003c\/p\u003e\u003cp\u003eThis U-bolt is used wherever 1-1\/2 inch pipe must be clamped and secured to a structural surface or support channel. Common applications include pipe hangers in residential and light commercial HVAC systems, plumbing supply and drain lines, refrigerant line sets, and general mechanical piping. The mount plate style allows direct attachment to flat surfaces without requiring a separate back plate. The hot galvanized coating makes it suitable for damp or outdoor environments such as rooftop mechanical units, crawl spaces, and exterior pipe runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound U-bolt profile sized for 1-1\/2 inch pipe\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread standard with 3 inch thread length for flexible mounting depth\u003c\/li\u003e\n\u003cli\u003eIntegrated mount plate for direct surface attachment without additional hardware\u003c\/li\u003e\n\u003cli\u003eC-1010 steel construction with hot galvanized finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eIncludes two nuts for complete installation\u003c\/li\u003e\n\u003cli\u003eWeighs 0.25 pounds — lightweight for overhead and confined-space installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pipe clamp replacement or new-installation fastener for 1-1\/2 inch nominal pipe in mechanical, plumbing, and HVAC piping support applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall by a licensed plumber, pipefitter, or HVAC technician per applicable mechanical codes such as the IPC or IMC.
