National Mfg N182-659 Threaded Rod Coupler 10-24 Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N182-659 is a zinc threaded rod coupler designed to join two pieces of threaded rod end-to-end in a single continuous run. Built to 10-24 UNC coarse thread standards, it provides a secure mechanical connection for suspended piping, conduit hangers, ductwork supports, and similar trade applications. The zinc construction offers basic corrosion resistance suitable for interior installations. Licensed HVAC technicians, plumbers, and electricians commonly use threaded rod couplers when assembling hanger rod assemblies from standard all-thread stock. This coupler ships in a package quantity of 40 units, making it practical for job-site stocking.

This coupler is suited for residential and light commercial mechanical and electrical installations where 10-24 UNC all-thread rod is used to suspend pipe, conduit, equipment, or duct. Typical applications include trapeze hangers, unistrut assemblies, and any rod-extension scenario where two lengths of threaded rod must be joined inline. The UNC coarse thread form is the standard used across most trade-supply all-thread rod stock in North America, ensuring broad compatibility with off-the-shelf rod material.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or electricians as part of hanger rod assembly work. Ensure both rod ends are fully threaded into the coupler before loading the assembly. Where witness holes are present on larger couplers in this series, visually confirm rod engagement through the hole before applying load. Follow applicable building codes, including IPC and IMC hanger spacing requirements, when sizing and placing rod supports.
