Value Collection -36674-1 Coupling Nut 5/8-11 Unc Steel

Product Description

The VALUE COLLECTION -36674-1 is a standard coupling nut designed to join or extend threaded rod, all-thread, or bolts in a continuous run. Machined to 5/8-11 UNC thread specification with a right-hand thread direction, this nut measures 2.125 inches overall length and features a 13/16-inch width across flats for standard wrench engagement. The steel construction is finished with a zinc plating for basic corrosion resistance. Coupling nuts of this type are standard hardware on mechanical, structural, and industrial assembly work across HVAC, plumbing, and general trade applications.

This coupling nut is suited for residential and commercial applications where threaded rod sections need to be connected end-to-end or where bolt length must be extended. Common installation scenarios include hanging threaded rod for pipe support, duct support, and equipment mounting. The 5/8-11 UNC thread size is a widely used coarse-thread standard, making this nut compatible with a broad range of hardware and fastener assemblies used by plumbers, pipefitters, HVAC mechanics, and general contractors.

Key Features

• 5/8-11 UNC coarse right-hand thread for broad compatibility with standard threaded rod and fasteners
• 2.125-inch overall length provides extended thread engagement compared to standard hex nuts
• 13/16-inch width across flats fits standard open-end or combination wrenches
• Zinc-plated steel finish offers basic corrosion protection for general indoor and protected installations
• Grade 2 steel material suitable for general-purpose mechanical fastening applications

Compatibility

Designed as a standard coupling nut for use with 5/8-11 UNC threaded rod, studs, or bolts in general mechanical and structural assembly applications.

Installation Notes

Coupling nuts are installed by licensed trades and general mechanics using standard hand or power tools. Always ensure mating threaded components are clean and free of debris before engagement. Thread both ends to equal depth for balanced load distribution. Do not use in applications exceeding the rated load capacity of Grade 2 steel fasteners.
