Value Collection -36674-4 Coupling Nut 1-8 Unc Steel

Product Description

The VALUE COLLECTION -36674-4 is a standard coupling nut designed to join two externally threaded fasteners end-to-end along a common axis. Built from steel with a zinc-plated finish, this hex coupling nut resists corrosion in typical indoor and light industrial environments. It carries a 1-8 UNC thread specification, a right-hand thread direction, and an overall length of 2.75 inches, making it well suited for applications that require an extended engagement length between threaded rods, studs, or bolts. The width across flats measures 1.375 inches. Installation requires only a standard open-end or combination wrench. Trades working in HVAC, plumbing, electrical, and general mechanical assembly use coupling nuts like this to extend threaded rod runs, anchor equipment frames, or connect all-thread rod segments.

This coupling nut sees use in residential and commercial construction and mechanical service work wherever two pieces of threaded rod or stud must be joined inline. Common applications include hanging duct, suspending pipe, anchoring electrical conduit supports, mounting equipment bases, and assembling strut and rod hanger systems. The 1-8 UNC thread standard is among the most common coarse-thread sizes in North American trade work, giving this fastener broad utility across a wide range of structural and mechanical assembly tasks.

Key Features

• 1-8 UNC coarse-thread profile for broad compatibility with standard threaded rod and studs
• Right-hand thread direction per UNC standard
• Zinc-plated steel construction provides corrosion resistance in typical service environments
• 2.75-inch overall length provides extended thread engagement for load-bearing connections
• 1.375-inch width across flats accepts standard open-end or combination wrenches
• Grade 2 steel meets general-purpose fastener requirements

Compatibility

Designed as a standard 1-8 UNC coupling nut for use with any 1-inch diameter, 8 threads-per-inch coarse-thread (UNC) threaded rod, stud, or externally threaded fastener conforming to UNC standards.

Installation Notes

Installation is performed with a standard open-end, combination, or adjustable wrench sized to the 1.375-inch width across flats. Thread both mating fasteners into the coupling nut by hand first to confirm thread engagement before applying torque. Inspect threads on both mating parts for damage before assembly. Follow applicable mechanical codes and project specifications for torque and load requirements.
