Abstract

A remote-controllable screw connection includes a nut, a first flange relvely closer to and a second flange relatively further away from the nut. At least one screw bolt connects the flanges to the nut. A sheath surrounds the screw bolt between the nut and the first flange. The sheath is non-rotatably but axially displaceably connected to the screw bolt.
