Torque control is used as automotive chassis parts tightening method. Torque controlled tightening method has axial force scatter of bolt. Axial force scatter should be minimized for robust chassis systems. This paper describe experimental analysis of bolt axial force scatter by ultrasonic bolt tension measurement about one time tightening and re-tightening method.
