National Marker N222075 Zinc Round U-bolt Pipe Fastener

Product Description

The NATIONAL MARKER N222075 is a zinc-plated round U-bolt designed for hanging and fastening applications across a range of trade and industrial settings. Part of the National catalog model 2190 series, this U-bolt measures 0.25 inches in diameter, 0.75 inches in width, and 2.5 inches in length. It is manufactured from steel with a zinc finish for corrosion resistance. Plate and hex nuts are included. This fastener is suitable for plumbers, automotive technicians, maintenance trades, and general industrial installers who need a reliable, hardware-complete pipe or structural fastening solution.

This U-bolt is primarily intended for use on pipe, with pipe sizes referenced as inside diameters of standard pipe. It is well suited for residential and light commercial plumbing applications, automotive work, and general home or industrial installations where a small-diameter round U-bolt is needed to secure or hang pipe, conduit, or rod stock to wood, metal, or structural members.

Key Features

• Zinc-plated steel construction for corrosion resistance in general-duty applications
• Round bend profile sized for standard pipe fitment based on inside pipe diameter
• Plate and hex nuts included for a complete, hardware-ready installation
• Compact dimensions of 0.25 x 0.75 x 2.5 inches suit tight-clearance mounting scenarios
• Suitable for automotive, plumbing, and general industrial fastening applications

Compatibility

Designed as an OEM-style fastening component compatible with standard pipe, wood, and structural members in automotive, plumbing, and general industrial applications where a 0.25-inch diameter round U-bolt is specified.

Installation Notes

Installation is typically performed by plumbers, maintenance mechanics, or automotive technicians using standard hand tools. Shut off water supply or de-energize any associated systems before securing pipe with U-bolts in live service lines. Ensure the mounting surface can support the load before tightening hardware. Do not overtighten hex nuts, as this may distort the pipe or crack the mounting substrate.
