Gibraltar GIB53023 Round U-bolt 1/4-20 Unc 3/4 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53023 is a round U-bolt designed to secure 3/4-inch pipe to structural supports in mechanical, plumbing, and HVAC piping systems. Manufactured from C-1010 steel with a hot galvanized finish, it provides corrosion resistance in both indoor and outdoor installations. The bolt features 1/4-20 UNC threading with a 1-1/2-inch thread length and an overall length of 3-1/8 inches. Two nuts are included for immediate installation without additional hardware. This fastener is specified by plumbers, pipefitters, and mechanical contractors when pipe hangers and supports require a reliable, code-compliant attachment point.

The GIB53023 is suited for residential and light commercial pipe support applications where 3/4-inch pipe runs need to be anchored to unistrut, threaded rod, or structural steel. Common applications include copper, steel, and CPVC supply lines in mechanical rooms, utility spaces, and overhead rough-in work. The round profile conforms to the pipe OD and distributes clamping load evenly. This style ships without a mount plate, making it compatible with strut-channel and similar framing systems where the installer provides the mounting surface.

Key Features

• Round U-bolt profile sized for 3/4-inch pipe with a 1-1/8-inch inner width

• Includes two nuts — no additional hardware required for basic installation
• Sold without mount plate for use with strut channel or custom mounting surfaces

Compatibility

Designed as an OEM-style support fastener for 3/4-inch pipe in mechanical and plumbing piping systems. Suitable for use with standard unistrut, strut channel, and threaded rod hanger assemblies where a 1/4-20 bolt pattern is specified.

Installation Notes

Installation is typically performed by licensed plumbers or mechanical contractors in accordance with applicable IPC and IFGC support spacing requirements. Shut off and depressurize the piping system before repositioning or modifying any pipe support. Use appropriate wrenches to tighten both nuts evenly against the mounting surface — do not over-torque, as this can deform the U-bolt or damage the pipe wall. Verify the galvanized finish is undamaged after installation; touch up any abraded areas in corrosive environments.
