Empire Industries 51SS0050K Coupling Nut 1/2-13 Stainless Steel

Product Description

The EMPIRE INDUSTRIES 51SS0050K is a standard rod coupling nut machined from T-304 stainless steel. It accepts 1/2-13 UNC right-hand thread and measures 1.25 inches overall length. Coupling nuts are used to join two externally threaded rods or fasteners end-to-end, extending threaded rod assemblies or connecting anchor bolts to all-thread. The T-304 stainless steel construction resists corrosion in wet, chemical, and outdoor environments, making this nut a reliable choice for mechanical, plumbing, and structural fastening applications. Electricians, plumbers, HVAC technicians, and general contractors install coupling nuts as part of pipe hangers, equipment supports, and threaded rod extensions. The bright, uncoated finish is typical for stainless hardware and requires no additional prep before installation.

This coupling nut is suited for residential and commercial applications where threaded rod extensions or bolt connections are required. Common install scenarios include pipe hanger assemblies, conduit support systems, equipment mounting frameworks, and structural tie-rod connections. The 1/2-13 UNC thread is one of the most widely used coarse-thread standards in North American trade work, and this nut is sized accordingly for standard all-thread rod stock of the same designation.

Key Features

• T-304 stainless steel construction for corrosion resistance in wet and outdoor environments
• 1/2-13 UNC right-hand thread matches standard all-thread rod and anchor bolt stock
• 1.25-inch overall length provides adequate thread engagement for load-bearing connections
• Bright, uncoated finish — no prep or treatment required prior to installation
• Suitable for mechanical, plumbing, electrical support, and structural fastening applications

Compatibility

Designed for use with standard 1/2-13 UNC right-hand threaded rod, all-thread, and fasteners conforming to that thread designation. Compatible with T-304 stainless or carbon steel threaded rod of the same thread specification.

Installation Notes

Install using an appropriately sized open-end or box wrench; avoid pipe wrenches or pliers that may damage the hex flats. Ensure mating threaded rod or fastener is clean and free of burrs before engaging threads. Do not mix stainless and dissimilar metals in environments where galvanic corrosion is a concern without appropriate isolation. Torque to project specification or applicable structural code requirements.
