Gibraltar GIB51560 Round U-bolt 5/8-11 Unc 6 Inch Pipe

Product Description

The GIBRALTAR GIB51560 is a round U-bolt designed to secure 6-inch pipe in mechanical, plumbing, and industrial piping installations. Built from C-1010 steel with a zinc-plated finish, it provides corrosion resistance in typical indoor and light-duty service environments. The fastener uses a 5/8-11 UNC thread with a 3-3/4 inch thread length, giving installers adequate engagement depth for standard hex nuts. Four nuts are included. This U-bolt ships without a mount plate, so it is intended for use with a separately sourced backing plate or structural support. Plumbers, pipefitters, and mechanical contractors are the primary installers.

This U-bolt is suited for securing 6-inch nominal pipe in residential and commercial mechanical rooms, utility spaces, and industrial piping runs. It is used where pipe must be clamped to a structural member such as unistrut channel, threaded rod hanger assemblies, or flat bar stock. The 5/8-11 UNC thread is a standard coarse-thread specification compatible with widely available hex nuts and washers. Applications include HVAC hydronic piping, plumbing supply and drain lines, and general mechanical pipe support work.

Compatibility

Designed as an OEM-style pipe support fastener for 6-inch nominal pipe in mechanical and plumbing pipe hanger assemblies requiring a 5/8-11 UNC round U-bolt without a mount plate.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or mechanical contractors. Shut off and depressurize the piping system before positioning any pipe support hardware. Torque nuts evenly on both threaded legs to prevent cocking the U-bolt and uneven load on the pipe wall. Pipe support spacing and load requirements should conform to applicable codes such as the International Plumbing Code or project-specific mechanical specifications.
