座金によるねじ締結体のねじ部トルク残留率の低減

抄録

In this study, many experimental data were collected by changing the properties of the contact surface of the bolt/nut/washer in order to obtain information on the thread torque residual rate after tightening with M12 hexagon bolts. Furthermore, the behavior of thread torque and clamp force was discussed based on the obtained experimental data.
