The present paper deals with the relation between the torque and axial tension of screw threads in the elastic-region tightening. The torque on fitted portion of threads and axial tension on the screw threads of M 12 × 1.5 - M 20 × 2.5 are measured by tightening test using a new designed device. The experimental results indicate that these measurement values are related to each other through the general equation that express the relation between torque on fitted portion of threads and axial tension in the screw threads. It is concluded that validity of the equation is confirmed experimentally, but the equation is not applicable when a bending moment acts upon the bolt at tightening.
