Value Collection 93570 Coupling Nut 1/4-20 Unc Stainless Steel

Product Description

The VALUE COLLECTION 93570 is a standard coupling nut machined from 18-8 and 303 stainless steel, designed to join two externally threaded fasteners along a common axis. The nut accepts a 1/4-20 UNC right-hand thread and measures 7/8 inch overall length with a 3/8 inch width across flats. Coupling nuts of this type are commonly used in threaded rod assemblies, tension rod systems, and extension applications where a single bolt or stud does not reach. The stainless steel construction provides corrosion resistance suited to moisture-exposed or outdoor environments. Installers in plumbing, electrical, HVAC, and general mechanical trades will recognize this fastener as a standard item for rod and stud extension work.

This coupling nut is suited for light-duty threaded rod joining in residential and commercial applications. Typical uses include extending all-thread rod in hanger assemblies, mechanical system supports, electrical conduit strut work, and equipment mounting. The 1/4-20 UNC thread standard is one of the most common unified coarse thread sizes in North American trade work, making this nut broadly applicable across mechanical and structural fastening tasks where a standard coupling length is sufficient.

Key Features

• 18-8 and 303 stainless steel construction for corrosion resistance in wet or outdoor environments
• 1/4-20 UNC right-hand thread for compatibility with standard unified coarse threaded rod and fasteners
• 7/8 inch overall length provides standard coupling engagement depth
• 3/8 inch width across flats fits standard open-end and box wrenches
• Sold in a package of 5 units

Compatibility

Designed as a standard coupling nut for use with 1/4-20 UNC threaded rod, studs, and bolts conforming to the Unified National Coarse thread standard.

Installation Notes

Installation requires a 3/8 inch open-end or box wrench. Thread both mating fasteners into the coupling nut with equal engagement depth on each side to maintain joint integrity. Ensure all threaded components share the same thread standard and direction before assembly. Stainless steel fasteners are susceptible to galling during installation; apply an appropriate anti-seize compound when joining stainless-to-stainless threaded connections.
