Value Collection 38774 Round U-bolt 3/8-16 Unc 3 Inch Pipe 2 Pack

Product Description

The VALUE COLLECTION 38774 is a round U-bolt designed to secure 3-inch pipe to structural supports without a mount plate. It features a 3/8-16 UNC thread standard with a 1-1/4 inch thread length, providing ample engagement for standard hex nuts. Constructed from C-1010 steel with a zinc-plated finish, the fastener resists corrosion in typical indoor mechanical and plumbing environments. Each package includes two U-bolts and two nuts, making it a ready-to-install solution for pipe support applications. The overall length measures 4-1/8 inches with a width of 3-1/2 inches to accommodate the specified pipe diameter.

This U-bolt is suited for use in residential and light commercial mechanical rooms, utility spaces, and pipe support installations where 3-inch pipe must be anchored to unistrut, beam clamps, or threaded rod assemblies. Plumbers, pipefitters, and mechanical contractors commonly use this style of fastener when installing drain, waste, vent, or process piping. The without-mount-plate configuration allows direct threading onto rod or structural steel without an additional backing plate.

Installation Notes

Installation is performed by licensed plumbers or mechanical contractors in accordance with applicable IPC and IFGC support spacing requirements for the pipe material and size. Before installation, ensure the supporting structure is adequately rated for the pipe load. Thread both included nuts onto the U-bolt legs and tighten evenly to avoid cocking the fastener against the pipe. Do not over-torque, as C-1010 steel at this diameter can be susceptible to thread stripping if forced beyond hand-snug plus standard wrench turns.
