Whether you call them coupling nuts or extension nuts, these parts attach threaded rods and other male-threaded fasteners. They often have a hex-shape construction for a wrench hole. However, they can also come in a round shape for specific applications. While hex coupling nuts look like an extended form of hex nuts, they have different applications.
The uses of a hex or round coupling nut include:
When searching for a coupling nut, it helps to understand how we note their sizes. A coupling nut's diameter should match the size of the fastener you plan to connect. In some projects, you need the threaded parts to connect to half of the coupling nut's thickness. In this situation, you can drill a hole in the middle of the nut to see where the fastener ends meet.
