Abstract: A machine tool device, particularly a hand-held machine tool device, includes at least one screw that is configured to secure at least one metal component to at least one additional component in a form-fitting manner. The machine tool further includes an electrical insulating unit that is configured to prevent the conduction of current at least between the metal component and the screw.

Abstract: A mechanical percussion mechanism for a percussion drive of a tool insert in a handheld power tool has a rotatably supported drive shaft, a percussion body connected to the drive shaft in a manner fixed against relative rotation and supported axially movable relative to the drive shaft, a rotatably supported driven shaft connected to the drive shaft in a manner fixed against relative rotation, the percussion body having drive cams and the driven shaft having drive cams, which drive cams of the percussion body and the driven shaft are bringable into operative connection for a percussion drive of the tool insert, and an axial stop provided for the percussion body.
