In this paper, a method to make the self-loosening-limit diagram is described based on the theory of mechanism of the self-loosening. The method is presented taking account of the characteristics of impulsive friction on the interfaces of fastener estimated from the results of the experiment in which the coefficient of impulsive friction on the test pieces is measured. The diagrams obtained by the method agree with the experimental results. And after the examination and comparison of those diagrams, the following fundamental items are found effective to prevent the loosening: (1) the compressive force on the interfaces still remains, even when the tensile stress waves arised from the external impact come to the interface of fastened pieces. (2) the actual compressive stress on the pressure flank does not exceed the compressive yield point.
