抜粋

A new measurement method of bolt tightening forces by simultaneous loading of torque and compressive force to a bolt has been developed. By simultaneous application of torque and compressive force to a bolt, the friction coefficients in threads and bearing surfaces are accurately detected separately in the process of tightening. Thus, the present method can control the tightening force of bolts within the error of ±10% for wide tightening forces under oil-free or lubricated conditions. The working efficiency of the present method is much better than that of the angle control method or the torque gradient control method because it is not necessary to measure the tightening angle and the friction coefficients in advance.
