National Marker N222364 Square U-bolt Zinc Plated Steel

Product Description

The National Marker N222364 is a zinc-plated square U-bolt manufactured from steel wire, designed to secure components to rectangular wood or metal surfaces. Sized at 5/16 inch diameter with a 2-inch width and 5-inch length, this U-bolt ships as an assembled unit including a bearing plate and two hex nuts, ready for immediate installation. The zinc finish provides corrosion resistance in standard indoor and light-duty outdoor applications. Licensed tradespeople and general contractors rely on this hardware for structural fastening tasks where a square bend profile is required over a round U-bolt configuration.

This U-bolt is suited for a range of fastening applications in construction, mechanical, and light industrial settings. The square bend geometry makes it particularly effective for clamping to rectangular tubing, lumber, and structural sections. Common uses include pipe and conduit anchoring, strut mounting, and equipment tie-down on rectangular framing members. Each unit is sold individually and packaged with all required mating hardware.

Installation Notes

Installation is typically performed by carpenters, pipefitters, electricians, or general mechanical tradespeople. Before installation, ensure the mounting surface is clean, structurally sound, and appropriate for the fastener load requirements. Thread both hex nuts evenly to prevent binding and achieve consistent clamping force across the bearing plate. Consult applicable building or mechanical codes for torque and fastening requirements specific to the application.
