Self-loosening phenomena in bolted joints result in serious accidents. Thus, several types of parts for preventing self-loosening have been applied to important bolted joints in mechanical structures. Recently, the prevailing torque type nuts, in which the friction coefficients are increased at the screw thread of nuts, have been paid a lot of attention and widely used in bolted joints for preventing self-loosening. In this paper, the self-loosening characteristics of bolted joints with the prevailing torque type nuts under repeated tensile loads were measured by general method and staircase method.
