Value Collection 203247 Coupling Nut 3/4-16 Unf Steel

Product Description

The VALUE COLLECTION 203247 is a standard coupling nut designed to join two externally threaded fasteners along a single axis. Machined from steel with a zinc-plated finish for corrosion resistance, this coupling nut features a 3/4-16 UNF right-hand thread and measures 2.25 inches overall length with 1 inch width across flats. Material Grade 2 construction makes it suitable for general mechanical assembly tasks in HVAC, plumbing, electrical, and industrial service applications. It is installed by hand with a wrench and does not require special tooling beyond standard hex wrenches or open-end spanners.

This coupling nut is used in applications where two threaded rods, bolts, or studs must be connected end-to-end, such as extending threaded rod runs for equipment hangers, pipe supports, electrical conduit racks, or structural mounting assemblies. The fine 3/4-16 UNF thread pitch provides good holding strength and precise adjustment capability, making it appropriate for both static load-bearing connections and adjustable support structures common in mechanical and electrical trades.

Key Features

• 3/4-16 UNF right-hand thread for precise fit on fine-thread fasteners
• 2.25 inches overall length for extended thread engagement between two fasteners
• Zinc-plated steel finish provides basic corrosion resistance in typical indoor service environments
• 1 inch width across flats allows installation with standard hex wrenches
• Material Grade 2 steel construction suitable for general-purpose mechanical assembly

Compatibility

Designed as a standard UNF coupling nut for use with 3/4-16 right-hand threaded rod or fasteners in general mechanical, HVAC, plumbing, and electrical support assembly applications.

Installation Notes

Coupling nuts of this type are installed by trade mechanics, HVAC technicians, electricians, and plumbers during equipment mounting and support structure assembly. De-energize and isolate any equipment before working on adjacent fastener assemblies. Apply appropriate thread lubricant or anti-seize compound if the installation environment involves moisture or dissimilar metals. Use the correct hex wrench size matching the 1 inch width across flats to avoid rounding the nut during tightening.
