Value Collection 250039 Coupling Nut 1/4-20 Unc Steel

Product Description

The VALUE COLLECTION 250039 is a standard coupling nut designed to join or extend two externally threaded fasteners along a common axis. Machined from steel with a zinc-plated finish for corrosion resistance, this hex coupling nut features a 1/4-20 UNC right-hand thread and measures 7/8 inch overall length with 3/8 inch width across flats. Grade 2 material meets standard load requirements for general mechanical assemblies. Electricians, HVAC techs, plumbers, and general trades use coupling nuts when extending threaded rod, mounting equipment, or joining all-thread in panel and bracket installations.

This coupling nut is suited for light- to medium-duty fastening applications across residential and commercial trade work. Common uses include threaded rod extensions in electrical conduit support, HVAC equipment mounting, pipe hanger assemblies, and general structural bracketing. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards in North American trade applications, making this nut broadly useful across fastener inventories.

Key Features

• 1/4-20 UNC coarse right-hand thread for broad compatibility with standard fasteners
• Zinc-plated steel finish provides basic corrosion protection in indoor and sheltered environments
• 7/8 inch overall length allows rod extension or joining in tight clearance situations
• 3/8 inch width across flats fits standard hex wrenches and sockets
• Grade 2 steel construction meets general-purpose mechanical load requirements

Compatibility

Designed as a standard 1/4-20 UNC coupling nut for use with any Grade 2 or equivalent 1/4-20 UNC threaded rod, bolt, or stud conforming to standard coarse-thread specifications.

Installation Notes

Installation requires a standard hex wrench or socket sized to 3/8 inch across flats. Ensure mating threaded components are clean and free of debris before threading to avoid cross-threading or galling. De-energize and lock out any electrical or mechanical system before installing fasteners in live panels or moving equipment. Do not exceed the load rating of Grade 2 hardware in structural or high-vibration applications.
