National Mfg N179-606 Zinc Threaded Rod 3/8-16 X 72 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-606 is a 72-inch zinc-plated threaded rod with 3/8-16 UNC coarse threads, sold in a package of 5. This fully threaded rod is designed for use in suspension, bracing, and anchoring applications across mechanical, plumbing, and electrical installations. The zinc plating provides basic corrosion resistance for dry and semi-exposed environments. With a minimum tensile strength of 6 KSI and conformance to ASTM A37 Grade A, this rod meets standard structural requirements for light-duty fastening and support work. It can be drilled, cut, heated, or shaped on the job site, giving installers flexibility during installation.

This threaded rod is commonly used in commercial and residential construction for hanging pipe hangers, conduit supports, ductwork strut systems, and equipment mounting assemblies. Its 72-inch length makes it suitable for full-length runs or field-cut shorter sections as needed. Mechanical contractors, electricians, and plumbers regularly use this type of rod with standard hex nuts, coupling nuts, and strut channel hardware to build out support frameworks for building systems.

Installation Notes

Installation is typically performed by licensed mechanical, electrical, or plumbing contractors as part of support and hanger assemblies. Use appropriate cutting tools such as a hacksaw or abrasive cut-off wheel when trimming to length, and deburr cut ends before threading nuts. Ensure mounting points meet applicable load requirements per local building codes before securing equipment or pipe loads. Always follow OSHA and applicable building code requirements when working with overhead support systems.
