Abstract: The most commonly used method to control the pre-tightening load of the bolt is torque measurement method and strain gauge method. The torque measurement method is convenient to use but usually leads to large control error, even up to ±25%. The strain gauge method is able to provide adequate control accuracy but is not convenient to use and costs are high. This study attempts to combine the advantages of the torque measurement method and the strain gauge method to form a kind of bolt pre-tightening force control method which is convenient for engineering application.
