" Common applications are linear actuators, machine slides (such as in machine tools), vises, presses, and jacks."

Square threaded screws, ACME screws, or power screws are all same and are used to transfer as much power through sliding surface of the screw.
They are used widely in Gate and globe valve stems. as well as to other mentioned by Fred.
