摘要：
A method and apparatus for tightening or loosening screw-type connections, in which the screw bolt is stimulated to oscillate longitudinally, the natural frequency of the bolt is measured and the excitation frequency is made to follow the changing natural frequency during the bolting process with a minimum, necessary excitation energy, so that the screw bolt attains a permanent state of resonance.
