Considering those productivity and maintenance, most of machine and product has many joints (fastening, welding and adhesive joint). 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 evaluated the self loosening behavior of thread joints under transverse cyclic loading. The limitative relative slippage which did not generate the Self loosening behavior was obtained by the result of cyclic loading and static loading tests. In addition, the limitative slippage was estimated according to the theoretical equation. Gradient coefficient of the bolt head of various bolts size was evaluated by the comparison of experimental results and analytical results.
