Product Description

The NATIONAL MARKER N222562 is a zinc-plated round U-bolt designed for hanging and fastening applications across a range of trade and industrial settings. Measuring 5/16 inches in rod diameter, 2-1/2 inches in inner width, and 5 inches in length, this U-bolt ships with plate and hex nuts included for a complete fastening assembly. The zinc finish provides corrosion resistance suitable for both indoor and light-duty outdoor use. It is used by plumbers, HVAC technicians, automotive service professionals, and general contractors who need a reliable, code-compatible pipe or structural fastener.

This U-bolt is primarily applied to pipe support and hanging installations, where the pipe sizes referenced correspond to the inside diameters of standard pipe. It is also used for fastening to wood framing, structural members, and similar substrates. Applications span residential and light commercial plumbing, automotive fabrication, and general industrial assembly. The included plate and hex nuts allow direct installation without sourcing additional hardware, making it suitable for service calls and retrofit work.

Installation Notes

Installation is typically performed by plumbers, HVAC technicians, or general contractors as part of pipe support or structural fastening work. Power down or isolate any pressurized systems before removing or replacing existing U-bolts on pipe runs. Use appropriately sized wrenches to seat the hex nuts evenly on both sides of the plate to ensure uniform clamping force. Refer to applicable IPC or local mechanical code requirements for pipe support spacing and fastener specifications.
