Value Collection 93571 Coupling Nut 5/16-18 Unc Stainless Steel

Product Description

The VALUE COLLECTION 93571 is a standard coupling nut designed to join two externally threaded fasteners along a common axis. Machined from 18-8 and 303 stainless steel, it resists corrosion in wet, humid, and mildly chemical environments. The nut carries a 5/16-18 UNC right-hand thread and measures 7/8 inch overall length with a 1/2 inch width across flats. Coupling nuts of this type are installed by electricians, plumbers, HVAC technicians, and general trade professionals wherever threaded rod extensions or all-thread connections are required.

This coupling nut is suited for light mechanical and trade applications where a standard UNC fastener is specified. Common uses include extending threaded rod for equipment hangers, pipe supports, conduit strut assemblies, and structural bracing. The stainless steel construction makes it appropriate for installations exposed to moisture, outdoor conditions, or corrosive atmospheres where carbon steel hardware would be unsuitable.

Key Features

• 5/16-18 UNC right-hand thread for standard fastener compatibility
• 18-8 and 303 stainless steel construction for corrosion resistance
• 7/8 inch overall length for compact inline thread extension
• 1/2 inch width across flats fits standard open-end and combination wrenches
• Sold in a pack of 5 units

Compatibility

Designed as a standard UNC coupling nut for use with any 5/16-18 UNC threaded rod, bolt, or stud conforming to unified coarse thread standards.

Installation Notes

Installation requires a standard open-end or combination wrench sized to 1/2 inch across flats. Thread both mating fasteners fully into the coupling nut and verify engagement length on each side before applying load. Follow applicable mechanical codes for minimum thread engagement requirements when used in structural or pipe-support applications. Avoid over-torquing, as stainless steel fasteners are susceptible to galling under excessive force.
