音波軸力測定ボルト。 In bolts that allow ultrasonic measurement of axial force even when the bolt thread is at high temperature by extending the bolt head, cooling that part locally, and attaching a sensor to the end face, there is a space between the bolt head and the outer periphery of the extended bolt head. An ultrasonic axial force measuring bolt characterized by being equipped with a heat-insulating tube that forms a
