National Mfg N179-465 Zinc Threaded Rod 5/8-11x24 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-465 is a zinc-plated threaded rod designed for general fastening, anchoring, and structural support applications across mechanical, plumbing, and construction trades. Measuring 5/8-11 inches in diameter with a 24-inch length, it features UNC coarse threads throughout. The rod is fabricated to ASTM A37 Grade A standards with a minimum tensile strength of 6 KSI, making it suitable for moderate-load fastening work. Its zinc finish provides basic corrosion resistance for indoor and sheltered outdoor use. The material responds well to common field modifications including drilling, cutting, heating, and shaping, giving installers flexibility on the job.

This threaded rod is used in residential and light commercial installations where a full-thread fastener is needed for hanger assemblies, bracing, pipe supports, equipment mounting, and similar structural connections. It is commonly used by plumbers, HVAC mechanics, and electricians to hang conduit, duct, pipe, and equipment from overhead structures. The 5/8-11 thread size is a widely used coarse-thread pitch that mates with standard coupling nuts, hex nuts, and strut channel hardware. Each package contains 5 rods.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or electricians as part of pipe, duct, or conduit support systems. Shut off and de-energize any adjacent systems before working overhead or in confined spaces. When cutting to length, use a thread-chasing die or file to clean thread ends before assembly. Follow applicable building codes and load ratings for hanger and support applications.
