Gibraltar GIB51005 Square U-bolt 3/8-16 Unc 2 Inch Steel

Product Description

The GIBRALTAR GIB51005 is a square U-bolt designed for securing pipe, conduit, tubing, or structural members to a supporting surface. Manufactured from C1010 steel with a zinc-plated finish for corrosion resistance, this fastener features a 3/8-16 UNC thread standard with a thread length of 1.5 inches and an interior width of 2 inches. The overall leg length is 3 inches. Hardware is included: two nuts and two washers ship with each unit. This U-bolt is installed by electricians, plumbers, HVAC technicians, and general contractors in a wide range of pipe and conduit support applications.

The GIB51005 is suited for residential and light commercial installations where a square-profile U-bolt is required to clamp round pipe or conduit against a flat structural surface. The square shape provides four-point contact geometry, making it appropriate for rigid pipe support runs. It is sold individually and is compatible with standard 3/8-16 hardware commonly stocked on service vehicles and in mechanical rooms.

Key Features

• Square profile provides stable four-point contact around pipe or conduit
• C1010 steel construction with zinc-plated finish for corrosion resistance
• 3/8-16 UNC thread for compatibility with standard hardware
• 1.5-inch thread length supports a range of clamping depths
• Includes two nuts and two washers for a complete installation
• No mount plate required, allowing direct installation to structural members

Compatibility

Designed as a standard-dimension square U-bolt for use with 3/8-16 UNC fastener systems in pipe support, conduit securing, and general mechanical fastening applications where a 2-inch interior width is required.

Installation Notes

Installation is typically performed by licensed plumbers, electricians, or HVAC technicians following applicable mechanical and electrical codes such as the NEC or IPC. Ensure the supporting structure is rated for the load before fastening. Thread the included nuts and washers evenly on both legs to avoid cocking the U-bolt during torque-down. Do not over-tighten on plastic or thin-wall pipe without appropriate pipe protection inserts.
