Value Collection 250119 Coupling Nut 1-8 Unc Steel

Product Description

The VALUE COLLECTION 250119 is a standard coupling nut used to join or extend threaded rod, all-thread, and fasteners with a 1-8 UNC thread form. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this coupling nut measures 2.75 inches in overall length with a 1.375-inch width across flats. The right-hand thread direction follows standard UNC conventions. Electricians, plumbers, HVAC installers, and general tradespeople use coupling nuts in strut assemblies, rod hangers, equipment mounts, and structural fastening applications.

This coupling nut is suited for general-purpose mechanical and structural fastening where 1-8 UNC threaded rod or studs are used. Common install scenarios include threaded rod extensions in pipe hangers, equipment support frames, electrical conduit supports, and ductwork suspension systems. The zinc-plated finish provides a baseline level of protection for interior and dry-to-mildly-humid environments. Sold individually, it fits standard 1-inch diameter UNC fastener assemblies found across residential and light commercial construction trades.

Installation Notes

Installation is performed using an open-end or adjustable wrench sized to the 1.375-inch width across flats. Thread both mating fasteners or rod sections fully and evenly into opposite ends of the coupling nut to ensure adequate thread engagement. De-energize or depressurize any system being worked on before installing or adjusting threaded rod assemblies. Follow applicable mechanical and structural codes for the specific application and loading requirements.
