FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used for tightening threaded joints. Method of tightening, consisting in applying torque to nut, measurement of current value of moment, nut turn at preset angle when nut reached set torque, stop of process of screwing nut after turning to preset angle, and repeated nut tightened until required value of moment is reached, when tightening nut turn angle is measured, after nut set value of torque is reached. At that, if after repeated tightening nut turn angle falls in field of tolerance formed by values of minimum and maximum tolerable angle of rotation of nut, connection is considered correctly tightened, if nut turn angle exits tolerance formed by minimum allowable and maximum tolerable angle of rotation of nut, coupling is tightened with defect.
EFFECT: detection of faulty tightened threaded connections.
