Abstract: An automatic screwing device, especially a hand screwdriver, consisting of a screwdriver and a collet to hold a secured protruding screw. The screwdriver is coupled to an actuating device so that it can rotate and move forward in relation to the collet. The actuating device has a first threaded element which can be driven rotationally and connected to the screwdriver and at least a second threaded element which is connected to the collet and interacts with the first threaded element. By providing two different thread pitches on the first and/or second element the screwdriver can advance at two different speeds while rotational speed of the first element remains the same.
