Value Collection 93575 Coupling Nut 5/8-11 Unc Stainless

Product Description

The VALUE COLLECTION 93575 is a standard coupling nut designed to join two externally threaded fasteners along a common axis. Machined from 18-8 and 303 stainless steel, this hex coupling nut resists corrosion in wet, chemical, and outdoor environments. It carries a 5/8-11 UNC right-hand thread and measures 2-1/8 inches overall length, with a 13/16-inch width across flats for standard wrench engagement. Coupling nuts of this type are installed by plumbers, pipefitters, electricians, HVAC technicians, and general tradespeople wherever threaded rod extensions or stud-to-stud connections are required.

This coupling nut suits residential and light commercial applications including threaded rod splicing, equipment mounting, and structural fastening tasks. The 5/8-11 UNC thread specification is common in trade applications where imperial coarse-thread fasteners are used with standard hardware and all-thread rod stock. The stainless steel construction makes it appropriate for installations exposed to moisture or mild corrosives, such as mechanical rooms, rooftop equipment supports, and outdoor utility mounts.

Compatibility

Designed as a standard replacement or installation coupling nut for 5/8-11 UNC threaded rod, studs, and fasteners in trade mechanical and structural applications.

Installation Notes

A licensed tradesperson or qualified installer should confirm thread engagement meets the requirements of the applicable mechanical or structural code before torquing. Use a properly sized open-end or combination wrench on the 13/16-inch flats; avoid pipe wrenches or pliers that can damage the hex surfaces. De-energize, depressurize, or otherwise isolate the assembly before replacing coupling nuts in live systems. Stainless fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into or onto stainless mating hardware.
