National Mfg N179-572 Zinc Threaded Rod 1/8x36 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-572 is a zinc-plated threaded rod measuring 1/8 inch in diameter by 36 inches in length. It features UNC coarse threads along its full length and meets ASTM A37 Grade A standards with a minimum tensile strength of 6 KSI. The zinc finish provides basic corrosion resistance for general indoor fastening and support applications. This rod is field-workable, meaning it can be drilled, cut, heated, and shaped on the job. Plumbers, HVAC technicians, and general contractors use threaded rods like this for pipe hangers, equipment supports, strut channel assemblies, and other mechanical fastening tasks.

This threaded rod is suited for light-duty residential and commercial applications where a field-adjustable fastener is needed. Common uses include suspending pipe runs, securing ductwork support hardware, mounting strut channel to structural elements, and building custom brackets. The 36-inch length gives installers enough stock to cut multiple shorter lengths from a single piece, reducing material waste on jobs with varied hanger drop requirements. Sold in a package of 2.

Key Features

• UNC coarse threads along full 36-inch length for broad hardware compatibility
• Zinc plating provides corrosion resistance for general indoor use
• Meets ASTM A37 Grade A standard with minimum tensile strength of 6 KSI
• Field-workable: can be drilled, cut, heated, or shaped without special tooling

• Sold in a package of 2 rods per unit

Compatibility

Designed as a general-purpose replacement or new-installation threaded rod compatible with standard 1/8 inch UNC coarse-thread nuts, couplings, and pipe hanger hardware used in HVAC, plumbing, and mechanical support assemblies.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical contractors following applicable local building codes and manufacturer hardware specifications. Use appropriate thread-cutting or pipe-cutting tools when trimming rod to length, and deburr cut ends before threading hardware. When used in support assemblies, verify that the combined load does not exceed the rated tensile strength of the rod. Ensure mating nuts and couplings are rated for UNC coarse thread engagement.
