What is Hex Coupling Nut Fastener?

A coupling nut, also known as extension nut, is a threaded fastener for joining two male threads, most commonly a threaded rod, but also pipes. The outside of the fastener is usually a hex so a wrench can hold it. Variations include reducing coupling nuts, for joining two different size threads; sight hole coupling nuts, which have a sight hole for observing the amount of engagement; and coupling nuts with left-handed threads. Coupling nuts, also called extension nuts, are used to join two threaded rods or pipes, including threaded rods or pipes of different sizes. Usually constructed in a hex shape for wrench hold, the most common uses for coupling nuts include tightening rod assemblies or to pushing a completed rod assembly outward. Coupling nuts are used to make up long tie rod assemblies from shorter lengths of rod and to facilitate assembly of two fasteners or fittings which both have external threads.
