Overtightening the screw is eliminated by the reliable torque
technology. Users have a distinct audible and perceptible
signal when releasing the torque.
Release accuracy is ±6% of the pre-set scale value, as
required by DIN EN ISO 6789.
To prevent users from damaging the blade or screw when
loosening a fastening, the tools limit the tightening torque, as
well as apply a special limit to the loosening torque to the
left; this is approximately 30 % greater than the tightening
torque.
