    摘要: A screw has a head whose underside has impressions or embossings and faces towards the tip. The underside is divided into at least five sectors of the same size. Three-fifths of the sectors exhibit an identical pattern of impressions or embossings and at least one sector is provided with a different pattern of impressions or embossings or else with no impressions or embossings.

    摘要: In a method for controlling a drive (4) of an electrically operated screwdriving power tool (2) during a screwdriving process, a tool holder (14) with a screw bit (16) fastened thereto is acted upon by the drive (4) to drive a fastening element (18) having a contact area (24) into a constructional component (20), with the screw bit movable up to a maximum screw-in value (Dmax) at a speed (D) and a operational torque (MA) generated between the screw bit (16) and the fastening element (18), and after it has been detected that a predetermined triggering screw-in depth (s0) has been reached, the speed (D) is reduced from the maximum screw-in value (Dmax) during a tightening process (AV), and, when it has been detected that a determined end value of the operational torque (MA) is reached, the screwdriving process is terminated.

    摘要: A control method for a screw including the following steps: a spindle (14) is driven by a motor (11) in order to turn a screw (19) around an axis of rotation (15). A magnetic field is generated around the turning screw (19). A modulation of the magnetic field caused by the turning screw (19) is detected by an active magnetic-field sensor (38). A switch-off criterion is selected by a screw-recognition device (28) on the basis of the detected modulation. The turning of the screw (19) is stopped by a switch-off device (24) as soon as the switch-off criterion is met.
