Abstract
The invention includes a fastening method and a fastening tool which can stably fasten a nut to a bolt securely and with a small dispersion at a desired axial force. A fastened member is fastened by inserting a bolt through the fastened member, thereafter temporarily positioning a nut and the bolt together, pulling a leading end of a shaft portion of the bolt in an axial direction of the bolt, rotating the nut so as to screw the nut into the bolt while elastically deforming the bolt so as to generate an axial force, and thereafter canceling the pulling of the bolt.
