ABSTRACT:
A hand-held device for driving screws into a receiving member or material includes a housing and an axially extending depth stop mounted on the front end of the housing. The depth stop is adjusted in the axial direction relative to the housing by an actuating sleeve which encircles a part of the depth stop and of the housing. The sleeve is connected to the depth stop by a pin and is axially movable between a first position where it is fixed to the housing and a second position where it is rotatable relative to the housing. Catch elements on the actuating sleeve and the housing hold the actuating sleeve in the first position. In the first position the pin fixes the actuating sleeve against rotation relative to the housing.
