Most of machine and products has many joints (e.g. fastening, welding and adhesive joints) for the efficient productivity and maintainability. Especially, the thread joint has been used the most mainly as a machine element. However, many troubles on strength and reliability of these machines and product are generating in these joints. In this paper, we have evaluated the sliding and the self loosening behavior of thread joints under transverse cyclic loading. The critical relative slippage (Scr), less than which thread joints can keep the fastening, was obtained by the result of cyclic loading tests. In addition, the torsion torque measurement of the volt was also carried out in order to examine the dependence of rotation looseness on releasing the elastic torsion of the bolt which occurs by the initial fastening.
