Threaded mating is used where secure mated condition is desired (or where connector interface characteristics require a specific amount of force), and space is available to turn the coupling nut.

The plug coupling nut is engaged with the jack threads and rotated, either hand-tight, or (for some series) to a specified torque.

For faster mating, some threaded types have double-lead threads.

For severe-vibration applications, most threaded connectors can be supplied with lockwire holes in the coupling nut.
