Thread torque of the bolt in bolted joints is .known to decrease after tightening, however, its mechanism has not been fully made clear. So the experiments and analysis on the behaviour of the thread torque have been performed for the case of the cylinder clamped by a bolt and nut. The main conclusions obtained in this study are as follows : (1) A method to predict the behaviour of the thread torque after tightening has been proposed for the abovementioned bolted joints. (2) The thread torque decreased after the tightening tool was removed in the tightening experiment, and the analytical results show good agreement with the experimental results. (3) The decrease of the thread torque was also caused by the repeated load, and its behaviour was well-simulated by the calculation.
