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. Coupling nut dimensions are described by the Industrial Fasteners Institute in standard IFI-128.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. Coupling nuts can be used to tighten a rod assembly inward or to press a rod assembly outward 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 holds, the most common uses for coupling nuts include tightening rod assemblies or pushing a completed rod assembly outward.

Coupling nuts (also known as a rod coupling, rod coupling nut, couplet nut or extension nut) is a threaded fastener for joining two male threads, most commonly threaded rods. The outside surface of the coupling nut is usually a hex shape to allow for wrench tightening. Reducing coupling nuts are a variant design that allows the joining of two rods of differing thread sizes.

FAQ
What is a coupling nut used for?

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 pushing a completed rod assembly outward.

What are round coupling nuts?

With a smooth rounded body for a finished look, use these nuts to connect and extend threaded rods. Black-oxide steel coupling nuts have mild corrosion resistance. 18-8 stainless steel coupling nuts have good chemical resistance.

How are coupling nuts measured?

Coupling nut size refers to its nominal thread diameter. Typically, sizes range from about #10 to 1 1/2″. Sizes less than 1/4″ appear as a number size (the larger the number the larger the size) while sizes that are 1/4″ and larger are specified in inches, usually fractional rather than decimal.

What are the three types of coupling?

The different types of coupling are Common-mode impedance (galvanic) coupling. Capacitive coupling. Inductive coupling.
