Value Collection 250358 Coupling Nut 1/4-28 Unf Steel

Product Description

The VALUE COLLECTION 250358 is a standard coupling nut designed to join two externally threaded fasteners along a common thread axis. Machined from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut measures 7/8 inches overall length with a 3/8-inch width across flats. The 1/4-28 UNF right-hand thread is a fine-pitch unified thread, providing tighter thread engagement and greater resistance to loosening under vibration compared to coarse-pitch alternatives. Electricians, HVAC technicians, plumbers, and general trade contractors use coupling nuts when extending threaded rod, connecting stud ends, or making inline threaded connections in light-duty mechanical assemblies.

This coupling nut is suited for light structural, mechanical, and trade fastening applications where a 1/4-28 UNF fine thread is specified. Common uses include threaded rod extensions, equipment mounting, conduit support assemblies, and general hardware connections in residential and commercial installations. The zinc-plated finish provides adequate protection in dry or mildly humid indoor environments. The compact 7/8-inch length makes it appropriate for confined-space installations where a longer coupling nut would interfere with adjacent components.

Key Features

• 1/4-28 UNF fine-pitch right-hand thread for secure engagement and vibration resistance
• Grade 2 steel construction provides adequate strength for light-duty fastening applications
• Zinc-plated finish offers basic corrosion protection in dry indoor environments
• 7/8-inch overall length suits confined-space and standard inline threaded connections
• 3/8-inch width across flats accepts standard combination or open-end wrenches

Compatibility

Designed for use with any 1/4-28 UNF right-hand threaded fastener, stud, or threaded rod conforming to unified fine thread standards.

Installation Notes

Installation requires a standard open-end or combination wrench sized for 3/8-inch width across flats. Ensure both mating fasteners share the same 1/4-28 UNF thread specification before assembly to avoid cross-threading. De-energize and de-pressurize any system before servicing components secured by this fastener. Do not exceed the load ratings appropriate for Grade 2 steel in structural or safety-critical connections.
