ABSTRACT:
In a method of tightening a screw member, the difference between the tightening axial force which is produced at the limit of elasticity when the friction coefficient between the screw member and a member into which the screw member is to be threaded is at a maximum and that when the friction coefficient between the screw member and the member into which the screw member is to be threaded is at a minimum is calculated, a seating torque is determined on the basis of the difference between the tightening axial forces, the screw member is threaded into the member into which the screw member is to be threaded until the tightening torque reaches the seating torque, and then the screw member is tightened by a predetermined angle.
