摘要： A method for simultaneous tightening of two or more screw joints to a desired pretension condition by means of a nut running tool having two or more output spindles each having an adjustable output torque, wherein each one of the output spindles is individually operated according to at least one primary tightening parameter from among torque, angular position, time, clampload, and screw joint elongation. An instantaneous value of the at least one primary tightening parameter is continuously detected for each one of the output spindles, and the instantaneous tightening parameter value for each one of said output spindles is continuously compared with a corresponding instantaneous tightening parameter value of each other one of the output spindles. A torque application speed is then continuously adjusted by continuously adjusting a limit of the output torque of one of the output spindles on which the instantaneous tightening parameter value exceeds a predetermined boundary in relation to any other one of the spindles.
