The scatter of bolt clamping force tightened by the conventional torque control method very often causes loosening and fatigue failure of bolted joints. Different values of frictional coefficients between mating screw surfaces and between mating bearing surfaces cause the scatter of clamping force in each tightening. In this study, a new tightening method to reduce the scatter of clamping force of bolted joints has been developed. In the new method, the frictional coefficients at screw and at bearing surface of bolt head can be separately detected during a tightening process by simultaneously application of tightening torque and compressive force to a bolt. The tightening experiments have been successfully conducted to demonstrate the efficiency and usefulness of the proposed method. Furthermore the optimum configuration of bolt head to improve the accuracy of the proposed method has been investigated.
