Empire 51G0058 Coupling Nut 5/8-11 Thread Zinc-plated Steel

Product Description

The EMPIRE 51G0058 is a standard coupling nut used to join or extend two externally threaded rods, bolts, or studs of the same thread size. Manufactured from steel with a zinc-plated finish, this fastener resists corrosion in typical indoor and light-duty service environments. The 5/8-11 unified coarse right-hand thread and 2.125-inch overall length make it a straightforward component for structural connections, hanging applications, and threaded rod assemblies. Electricians, plumbers, HVAC techs, and general contractors reach for coupling nuts when extending all-thread rod in suspended ceiling grids, pipe hangers, equipment mounts, and similar trade installations.

This coupling nut is suited for light commercial and residential trade applications wherever 5/8-11 threaded rod or hardware requires extension or joining. Typical uses include mechanical system hangers, unistrut assemblies, equipment support rods, and general fastening tasks that call for a standard unified coarse hex coupling nut. The zinc-plated finish is appropriate for dry or mildly humid indoor environments.

Key Features

• 5/8-11 unified coarse right-hand thread for broad hardware compatibility
• 2.125-inch overall length provides sufficient engagement for secure rod-to-rod joining
• Steel construction delivers solid tensile strength for structural hanging and support tasks
• Zinc-plated finish adds corrosion resistance for indoor and light-duty service conditions
• Compact weight of 0.18 pounds keeps assembly weight low in overhead installations

Compatibility

Designed as a standard 5/8-11 coarse-thread coupling nut compatible with any 5/8-11 threaded rod, bolt, or stud conforming to unified coarse thread standards.

Installation Notes

Installation requires no special tools beyond a wrench sized for the hex flats of the coupling nut. Verify that mating threaded rod or fasteners share the same 5/8-11 coarse thread specification and right-hand thread direction before assembly. Ensure adequate thread engagement on both ends of the nut for full load-bearing capacity. For overhead or structural applications, follow applicable building codes and load rating guidelines for the full fastener assembly.
