National Mfg N179-416 Zinc Threaded Rod 1/4-20 X 24 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-416 is a 1/4-20 zinc threaded rod measuring 24 inches in length, designed for general fastening, hanging, and support applications across mechanical, plumbing, and construction trades. It features UNC coarse threads and is fully workable — it can be drilled, cut, heated, and shaped in the field to meet specific installation requirements. The zinc finish provides basic corrosion resistance for indoor and light-duty applications. Minimum tensile strength is 6 KSI, with a safe working load (SWL) of 650, making it suitable for light structural support and component hanging tasks.

This threaded rod is used in residential and light commercial settings where adjustable-length fastening solutions are needed. Typical applications include HVAC duct hangers, pipe support straps, electrical conduit supports, and equipment mounting. The 1/4-20 UNC thread pattern is one of the most common coarse-thread sizes in trade work, ensuring compatibility with standard nuts, couplers, and threaded inserts. Sold in a package quantity of 5 rods, it suits both stocking and job-specific use.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or electricians as part of pipe, duct, or equipment support assemblies. Cut to length using a hacksaw or angle grinder and deburr cut ends before threading hardware. Always verify that the SWL and tensile rating are appropriate for the intended load before installation. Follow applicable mechanical and building codes for hanger spacing and support requirements.
