PROBLEM TO BE SOLVED: To provide a torque tool device which can positively identify which torque device has carried out bolt fastening, and to provide a torque tool device which can obtain the traceability of items such as a torque standard and the torque tool. SOLUTION: When a torque wrench 1 carries out bolt fastening, it transmits the production number thereof and fastening data including a measured torque value to a processing terminal 20 as a set. The processing terminal 20 transmits the production number and the fastening data to an outside connected equipment 30 which then records the fastening data and data including fastened bolts, for each production number. Thus the torque wrench 1 can be identified from the fastened bolt, and the traceability can be achieved. COPYRIGHT: (C)2009,JPO&INPIT
