Value Collection -36668-1 8-32 Unc Coupling Nut 5/8 Inch

Product Description

The VALUE COLLECTION -36668-1 is a standard coupling nut designed to join two externally threaded fasteners in a single inline connection. Manufactured from steel with a zinc-plated finish, this nut carries an 8-32 UNC right-hand thread and measures 5/8 inch overall length with a 5/16 inch width across flats. The zinc plating provides a baseline level of corrosion resistance suitable for general-purpose indoor mechanical and electrical enclosure assembly. It conforms to Material Grade 2 standards and follows Unified National Coarse thread specifications, making it a reliable choice for standard fastening applications across trade and industrial settings.

This coupling nut is used wherever two threaded rods, studs, or bolts must be connected end-to-end along the same axis. Common applications include HVAC equipment mounting, electrical panel standoffs, plumbing support rods, and general mechanical assembly. The compact 5/8 inch OAL makes it well suited for tight-clearance installations where a full-length coupling nut would not fit. Installers across HVAC, electrical, and plumbing trades encounter this fastener size in everyday service and new-construction work.

Key Features

• 8-32 UNC right-hand thread for compatibility with standard coarse-thread fasteners
• 5/8 inch overall length for use in tight-clearance applications
• 5/16 inch width across flats for use with standard open-end or box wrenches
• Steel construction with zinc-plated finish for corrosion resistance in general indoor environments
• Material Grade 2 construction meeting standard mechanical fastener specifications
• UNSPSC Code 31161728 for procurement and catalog classification

Compatibility

Designed as a standard replacement or stock coupling nut for any application requiring an 8-32 UNC right-hand thread, 5/8 inch OAL coupling nut in steel with zinc-plated finish.

Installation Notes

Installation requires only a standard open-end or box wrench sized to 5/16 inch width across flats. Power down or de-energize any electrical panel or mechanical system before accessing fastener points in live equipment. Inspect mating threads on both fasteners for damage or contamination before threading the coupling nut onto either end. Do not overtighten; apply only hand-snug torque followed by minimal wrench turns appropriate for Grade 2 steel fasteners in the application.
