A coupling nut, also known as an extension nut, is a type of threaded fastener with internal threads at both ends. It is designed to connect two threaded components, such as threaded rods or bolts, effectively extending their length or joining them together. Coupling nuts are commonly used in various applications where it is necessary to extend, couple, or join threaded parts.


Coupling nuts are versatile and provide a simple solution for extending or connecting threaded components. They come in various sizes and materials to accommodate different thread sizes and environmental conditions. The choice of coupling nut size and material depends on the specific requirements of the project or application.
