Gibraltar GIB51145 Square U-bolt 3/8-16 Unc Stainless Steel

Product Description

The GIBRALTAR GIB51145 is a square U-bolt manufactured from 304 stainless steel, designed for secure pipe, conduit, and structural clamping applications in trade and industrial environments. It features a 3/8-16 UNC thread with a thread length of 5-5/8 inches and an overall length of 9 inches. The square bend geometry maintains consistent spacing and load distribution across the clamped surface. Each unit ships with two nuts and two washers. Plumbers, pipefitters, electricians, and mechanical contractors use square U-bolts where a flat, stable clamping profile is required and corrosion resistance is a priority.

This U-bolt is suited for pipe support, conduit strapping, and structural attachment in corrosive or outdoor environments where stainless steel is specified over zinc-plated hardware. The 6-inch width accommodates larger-diameter pipe or tube runs. It is commonly installed on unistrut, threaded rod hangers, or direct-mount structural members in commercial mechanical rooms, marine environments, and wastewater facilities. No mount plate is included, making it compatible with installations where the mounting surface is handled separately or where a saddle-style clamp is not required.

Key Features

• 304 stainless steel construction resists corrosion in wet, outdoor, and chemical-exposure environments
• Square bend profile provides flat, stable contact against pipe or conduit surfaces
• 3/8-16 UNC thread standard for broad compatibility with standard nuts and hardware
• 5-5/8 inch thread length accommodates varying material thickness and clamping depth
• Includes two nuts and two washers for a complete fastening assembly out of the package
• No mount plate configuration allows flexible integration with existing strut or structural hardware

Compatibility

Designed as a standard square U-bolt for pipe support, conduit clamping, and structural fastening applications requiring 3/8-16 UNC hardware and a 6-inch inside width.

Installation Notes

Installation is typically performed by plumbers, pipefitters, or electricians depending on the application. Shut off and de-energize or depressurize any system before attaching or adjusting pipe or conduit supports. Use appropriate wrenches to seat the nuts evenly on both legs of the U-bolt to prevent uneven loading. Consult local mechanical and electrical codes, including IPC and NEC references, for required support spacing and hardware specifications.
