Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-515 is a zinc-plated threaded rod measuring 3/8-16 inches in diameter by 36 inches in length, featuring UNC coarse threads throughout its full length. This all-thread rod is designed for use as a fastening, hanging, or support element in mechanical, plumbing, HVAC, and general construction applications. The zinc coating provides basic corrosion resistance for indoor and light-duty outdoor use. It meets ASTM A37 Grade A standards with a minimum tensile strength of 6 KSI, making it suitable for standard-load fastening tasks performed by licensed tradespeople and skilled installers.

This threaded rod is used across a wide range of trade applications including HVAC duct hanger systems, pipe support assemblies, electrical conduit supports, and general mechanical fastening. Its 36-inch length allows it to be cut to required lengths on the job site.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or electricians as part of pipe, duct, or conduit support systems. Cut the rod to the required length using a reciprocating saw or hacksaw, and chase cut threads with a die if needed to ensure clean thread engagement. Shut off and de-energize any systems in the work area before installing overhead supports. Follow local building codes and applicable standards such as the IPC or IFGC for hanger spacing and load requirements.
