PCT No. PCT / EP97 / 05974 Sec. 371 Date Jul. 16, 1999 Sec. 102(e) Date Jul. 16, 1999 PCT Filed Oct. 29, 1997 PCT Pub. No. WO98 / 22263 PCT Pub. Date May 28, 1998A power screwdriver has a drive unit and an input circuit for inputting screw size, material quality, pitch, and clamping length of a screw. An evaluation circuit is provided for determining a nominal prestress force based on input screw size, material quality, and clamping length, for determining a nominal torque based on the nominal prestress force and the pitch, and for determining the screw clamping angle resulting from the nominal prestress force and the pitch. A sensing device for sensing the actual torque is provided, and a further sensing device for sensing the actual screw clamping angle is present. A control and switch-off device controls further rotation of the drive unit when the actual torque coincides with the nominal torque and switches off the drive unit when the actual screw clamping angle coincides with the nominal screw clamping angle. The nominal torque, based on which the additional rotation o f the drive unit is controlled until the nominal screw clamping angle is reached, is set to a value which is smaller than the torque corresponding to the nominal pretension force. An additional rotation angle of the drive unit, for reaching the nominal screw clamping angle corresponding to the nominal prestress force, is determined based on the difference between the nominal screw clamping angle and the adjusted screw clamping angle corresponding to the preset nominal torque and is used for switching off the drive unit.
