FASTENING MANAGEMENT SYSTEM OF SCREW

PROBLEM TO BE SOLVED: To achieve reduction of assembly cost of an airplane and achieve efficiency of fastening work of a screw by achieving the highly reliable fastening work of the screw by even one worker in the assembly process of the airplane. SOLUTION: The fastening management system 1 of the screw has a management device 4 for storing the data of the set torque value of the screw corresponding to respective identification codes 3 attached to the components 2 of the airplane; a mobile information terminal 5 for reading the identification codes 3, wirelessly transmitting them to the management device 4 and capturing a corresponding set torque value from the data; and a manual torque wrench 6 for fastening the screw with the captured set torque value. The manual torque wrench 6 has a torque detection means 6a which detects torque information acting on the screw and wirelessly transmits it to the management device 4. The management device 4 has a determination means 4b for determining whether or not the screw is fastened to the set torque value based on the torque information and when determined to be fastened wirelessly transmitting fastening completion information to the mobile information terminal 5 so as to inform the fastening completion of the screw.
