Value Collection 250106 Coupling Nut 7/8-9 Unc Steel

Product Description

The VALUE COLLECTION 250106 is a standard coupling nut used to join two externally threaded fasteners end-to-end along a common axis. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this coupling nut carries a 7/8-9 UNC right-hand thread and measures 2.5 inches overall length with 1.25 inches across the flats. It is a general-purpose hex coupling nut suited for use in mechanical assemblies, structural connections, and trade installations where extended thread engagement or threaded rod splicing is required. Electricians, plumbers, HVAC mechanics, and general contractors reach for coupling nuts when anchoring threaded rod to structure or extending bolt length.

This coupling nut is appropriate for residential and light commercial applications involving threaded rod hangers, pipe strut systems, and equipment mounting assemblies. The 7/8-9 UNC thread designation is a coarse-thread standard common in structural and mechanical fastener applications across North American trade work. The zinc-plated finish provides a measure of protection in dry to mildly humid interior environments.

Key Features

• 7/8-9 UNC right-hand coarse thread for compatibility with standard inch-series threaded rod and bolts
• Grade 2 steel construction provides adequate tensile strength for general mechanical and structural use
• Zinc-plated finish offers basic corrosion resistance in dry interior environments
• 2.5 inches overall length provides extended thread engagement for rod-splicing applications
• 1.25 inches width across flats accepts standard open-end or box wrenches
• Hex profile allows torque application from standard hand or power tools

Compatibility

Designed for use with 7/8-9 UNC threaded rod, bolts, and fasteners conforming to inch-series coarse-thread standards commonly used in structural and mechanical trade assemblies.

Installation Notes

Installation is performed by hand-threading the coupling nut onto mating 7/8-9 UNC fasteners, then tightening with an appropriately sized open-end or box wrench. Verify that both mating fasteners share the same thread standard and direction before assembly. Follow applicable mechanical or structural codes for the installation environment, including torque requirements specified by the design engineer or applicable building code. Use of thread-locking compound or jam nuts may be appropriate in applications subject to vibration.
