Value Collection 93574 Coupling Nut 1/2-13 Unc Stainless Steel

Product Description

The VALUE COLLECTION 93574 is a standard coupling nut used to join or extend threaded rod, all-thread, or externally threaded fasteners in a straight-line connection. Manufactured from 18-8 and 303 stainless steel, this nut resists corrosion in wet, humid, and mildly corrosive environments. It carries a 1/2-13 UNC thread with a right-hand thread direction, an overall length of 1-1/4 inches, and a width across flats of 5/8 inches. Sold in a package quantity of two. Electricians, plumbers, HVAC technicians, and general tradespeople use coupling nuts wherever threaded rod extensions or long-bolt assemblies are required.

This coupling nut is suited for both light commercial and residential applications where stainless steel hardware is specified for corrosion resistance. Common uses include hanging threaded rod assemblies, pipe hanger systems, mechanical equipment supports, and electrical unistrut installations. The 1/2-13 UNC thread is one of the most widely used coarse-thread sizes in North American trade work, making this nut a practical stock item for field kits and service vans. Installers working with 316 or marine-grade requirements should verify material grade suitability before use.

Key Features

• 18-8 and 303 stainless steel construction provides corrosion resistance in wet and humid environments
• 1/2-13 UNC coarse thread for compatibility with standard North American threaded rod and fasteners
• Right-hand thread direction for standard installation with conventional tools
• 1-1/4 inch overall length provides sufficient thread engagement for secure rod-to-rod connections
• 5/8 inch width across flats fits standard open-end, combination, and adjustable wrenches
• Packaged in quantities of two for small-quantity procurement

Compatibility

Designed for use with 1/2-13 UNC right-hand threaded rod, all-thread bar, and externally threaded fasteners in standard trade hardware assemblies.

Installation Notes

Installation requires a standard open-end or adjustable wrench sized for a 5/8 inch hex. Thread both mating fasteners or rods fully into the coupling nut and verify thread engagement is even on both ends before applying final torque. When used in pipe hanger or equipment support assemblies, follow applicable mechanical and structural codes for load ratings. Stainless fasteners are subject to galling — applying a compatible anti-seize compound before assembly is standard practice.
