Value Collection 38763 Round U-bolt 5/16-18 Unc 1-1/4 in Pipe

Product Description

The VALUE COLLECTION 38763 is a round U-bolt designed to secure pipe runs to structural supports without a mount plate. Made from C-1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt fits 1-1/4 inch pipe and features a 5/16-18 UNC thread on each leg. Thread length measures 1-1/8 inches, providing adequate engagement for the included hex nuts. Each package contains five U-bolts, each supplied with two nuts. This hardware is used by plumbers, pipefitters, HVAC installers, and mechanical contractors in standard pipe support applications.

This U-bolt is sized for 1-1/4 inch nominal pipe and is suited for residential and light commercial mechanical systems where threaded rod or flat bar support structures require a round-profile clamp without an integrated mount plate. The zinc-plated finish provides basic protection against moisture exposure in indoor mechanical rooms, utility spaces, and crawlspace installations. The round shape wraps the pipe evenly to distribute clamping load without deforming the pipe wall.

Designed as a standard-fitment round U-bolt for 1-1/4 inch nominal pipe support applications using 5/16-18 UNC threaded hardware.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC mechanics following applicable mechanical code requirements. Shut off and depressurize the pipe system before positioning supports. Thread both included nuts onto the U-bolt legs and tighten evenly to prevent pipe misalignment. Do not overtighten against plastic-lined or soft-wall pipe without an appropriate liner or saddle.
