This paper is an experimental research study aimed at the future realization of tightening of the F10TW by the nut rotation method in the actual work. In this study, using a bolted joint test body with a pressure film type inorganic zinc rich paint on the contact surface, an introduction axial force test and a relaxation test were conducted to examine the nut rotation angle that can satisfy an appropriate bolt axial force. Also, the slip resistance was clarified.
