The high frequency bolt heater of the torque system is used by inserting a water-cooled work coil into the thermocouple heater hole / measurement hole. The alternating magnetic flux generated from the work coil by the alternating current penetrates inside the bolt to induce a very dense eddy current, and the Joule heat heats the bolt. Heat is conducted outward from the center hole of the bolt, and the bolt is thermally expanded to turn the nut. Unlike conventional electric heating type bolt heaters, only the necessary parts are heated with appropriate power, so unnecessary temperature rise is suppressed and the material of the bolt itself is not affected..
