Gibraltar GIB51105 Square U-bolt 3/8-16 Unc Stainless Steel

Product Description

The GIBRALTAR GIB51105 is a square U-bolt designed for securing pipe, conduit, or structural members to a mounting surface. Manufactured from 304 stainless steel, it resists corrosion in wet, outdoor, and chemically exposed environments. The 3/8-16 UNC threaded ends offer 1.5 inches of thread engagement, providing solid clamping force without a mount plate. Each unit ships with two nuts and two washers, giving the installer everything needed to complete the fastening assembly. Plumbers, pipefitters, electricians, and general contractors specify this hardware for pipe support, cable management, and light structural clamping tasks where corrosion resistance is required.

This U-bolt suits residential and commercial applications where stainless steel fasteners are specified, including marine environments, mechanical rooms, outdoor installations, and anywhere galvanic or moisture-related corrosion is a concern. The square bend geometry matches square or rectangular tube stock and framing members. It is sold individually and is appropriate for use with standard 3/8-inch hardware throughout the assembly.

Key Features

• Square bend profile fits square and rectangular tube or channel
• 304 stainless steel construction for corrosion resistance in wet and outdoor environments
• 3/8-16 UNC thread standard for compatibility with widely available hardware
• 1.5 inches of thread length provides adequate clamping depth

• No mount plate design for direct surface or bracket mounting

Compatibility

Designed as a direct-install square U-bolt for use with standard 3/8-16 UNC threaded hardware in pipe support, conduit strapping, and structural clamping applications.

Installation Notes

Installation is typically performed by plumbers, pipefitters, or electricians as part of pipe or conduit support systems. Power down any energized circuits and depressurize piping before working in the immediate area. Use appropriately rated wrenches or sockets for tightening 3/8-16 nuts; do not overtighten, as stainless steel fasteners are susceptible to galling. Follow applicable codes such as the IPC or NEC for required pipe and conduit support spacing and fastener specifications.
