1/4-20 Zinc-Plated Coupling Nuts

This pack contains one hundred coupling nuts with 1/4-20 threads. Each nut is made from steel and finished with a zinc plating for corrosion resistance. The overall length is seven-eighths of an inch. They are supplied new in a bulk quantity for workshop or job-site use.

For installers joining threaded rod

These nuts suit electricians, plumbers and maintenance crews who need to extend or connect 1/4-20 threaded rod in conduit, strut or hanger assemblies. The zinc finish handles indoor and light outdoor exposure. Builders who require stainless steel for marine or chemical environments should look at a different material.

Fits 1/4-20 rod and frees inventory space

The nuts thread directly onto standard 1/4-20 rod without adapters. A single box of one hundred pieces covers multiple jobs, reducing re-order frequency. The compact package stores easily on a shelf or in a service vehicle, keeping the fastener supply ready for the next installation.

Questions about this item

What thread size must the rod or bolt have to fit the 1/4-20 coupling nut?

The nut uses a 1/4-20 thread, so the mating rod or bolt must be 1/4-20 to engage correctly.

Will the zinc-plated steel nuts gall or seize when paired with older plain-steel threaded rod?

Zinc plating reduces galling compared to bare steel, but lubricating the threads during assembly is still recommended for smooth engagement.
