Value Collection 202290 Coupling Nut 5/16-18 Unc Zinc-plated

Product Description

The VALUE COLLECTION 202290 is a standard coupling nut used to join or extend two externally threaded fasteners along a single axis. Machined from steel with a zinc-plated finish for basic corrosion resistance, this nut features a 5/16-18 UNC right-hand thread and measures 7/8 inches overall length with 1/2 inch width across flats. The hex profile allows standard wrench engagement for secure installation. At 0.035 pounds, this is a lightweight, general-purpose hardware component suited for mechanical assemblies, equipment mounting, and threaded rod extensions across HVAC, plumbing, and electrical trade applications.

Coupling nuts in this thread size are commonly used in residential and light commercial mechanical work where threaded rod sections must be joined or where a stud needs to be lengthened to reach a mounting surface. The 5/16-18 UNC thread standard is widely used in equipment mounting, ductwork hanging hardware, and general structural fastening. Licensed tradespeople and maintenance technicians across multiple disciplines use this fastener in everyday service and installation work.

Key Features

• 5/16-18 UNC right-hand thread for broad fastener compatibility
• Zinc-plated steel finish provides basic corrosion resistance in dry to mildly humid environments
• 7/8 inch overall length suits standard coupling applications without excessive bulk
• 1/2 inch width across flats fits standard combination wrenches and sockets
• Material Grade 2 steel construction for general-purpose mechanical use

Compatibility

Designed for use with any 5/16-18 UNC externally threaded fastener, stud, or threaded rod conforming to Unified National Coarse thread standards.

Installation Notes

Installation requires a standard 1/2 inch wrench or socket. Ensure mating threaded components are clean and free of debris before engagement to avoid cross-threading. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners in the 5/16-18 thread class. Always follow applicable mechanical and structural codes for the specific trade application.
