National Mfg N179-457 Zinc Threaded Rod 1/2-13x24 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-457 is a zinc-plated threaded rod measuring 1/2-13 x 24 inches with UNC coarse threading. This all-thread rod is used to create fastening assemblies, suspension supports, and structural connections in mechanical, plumbing, and electrical installations. It carries a minimum tensile strength of 6 KSI and a safe working load (SWL) of 3,100 pounds. The zinc finish provides basic corrosion resistance for indoor and light-duty applications. Trade professionals install this rod as a hanger, anchor, or tension member wherever a continuous threaded fastener is required.

This threaded rod is suited for residential and light commercial construction and mechanical system installations. Common applications include pipe hangers, equipment supports, electrical conduit strut assemblies, and structural tie-rod work. The rod can be drilled, cut, heated, or shaped on the job site to meet specific length or configuration requirements. It meets ASTM A37 Grade A material standards. Sold in a package quantity of 5 rods.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, electricians, or general mechanical contractors. Disconnect or de-energize any adjacent systems before cutting or shaping the rod in an occupied space. When cutting to length, dress the cut end to remove burrs before threading on nuts or couplers. Follow applicable codes such as the IPC, IFGC, or NEC for hanger spacing and load requirements specific to the system being supported.
