Screw Jack

A screw jack, also known as a leadscrew jack, is a type of mechanical device that uses the principle of helical threads to convert rotational motion into linear movement. This jack consists of a threaded rod (the leadscrew) with a nut attached to a load, which moves up or down along the screw as it turns. The pitch and diameter of the screw determine the amount of linear displacement achieved per rotation, making it an ideal tool for raising or lowering heavy loads in various applications.
