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

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.
