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. These are used to make up long rod

assemblies from shorter lengths of rods. The rods are threaded into the coupling

nut for a certain distance. Coupling nut dimensions are described by the Industrial

Fasteners Institute in standard IFI-128. It is given a plain finish. It is either cold

drawn or hot rolled depending on the bar stock used. Coupling nuts threaded

with two different thread sizes and profiles are called reducing coupling nuts.

Coupling nuts can be used to tighten a rod assembly inward or to press a rod

assembly outward

Metric DIN 6334 Hexagon Coupling Nuts also known as extension nuts

are elongated fully threaded hex nuts that often used to join two

externally threaded fasteners usually threaded rods. DIN 6334 metric

hex nuts have a height of 3 x the major diameter of the thread.
