A preferably portable tightening tool contains torque and angle sensors which are attached to an analog computing circuit which determines an end cut-off parameter during tightening below the elastic limit of each part of the joint to be tightened. The end cut-off parameter has a different value for each joint during the individual tightening of several, essentially identical joints. In an embodiment of the invention, a simplification is effected by measuring an angular interval lying between two predetermined torque values. In a further embodiment of the invention, a simplification is effected by measuring the torque value which is present at a predetermined angular interval after a first predetermined torque value is reached. <IMAGE> |
