Abstract: An electric hand tool has a driving unit for driving a shaft of the electric hand tool and configured to drive, via the shaft, a socket of the electric hand tool or a socket connectable to the electric hand tool; a torque sensor for measuring a torque applied to the shaft via the driving unit; a control unit for controlling the driving unit to limit the measured torque to a predetermined value and/or to adjust the measured torque to the predetermined value within a tolerance range; and a transmitter for transmitting data from the electric hand tool to an external memory, the data comprising a final torque value. A method provides a traceable logging of a torque value and issuance of a corresponding certificate.
