The bolts and nuts are widely used in various fields as important joining elements withlong history. However, loosening induced by the vibration and external loads is still a big problem.And the loosening sometimes causes very serious accident without notice. This paper deals with aspecial stud bolt named “Super Stud Bolt (SSB)” which can prevent loosening effectively. There isa thin walled tube between the upper and lower threads, which can be deformed along the axialdirection so that the phase difference is produced and SSB is developed. This phase differenceinduces the contrary force on the surfaces of the upper and lower threads, which brings out theanti-loosening performance. In this study, the processing and fastening-loosening courses aresimulated with the finite element method. And the anti-loosening performance is analyzed andrealized. In addition, the anti-loosening performances under various phase differences are comparedand finally best dimensions for SSB are examined
