The loosening of inter- hexagonal screws connecting internal parts in main pump for nuclear power station causes some nuclear safety problem due to medium erosion at present. Aim at the problem, a special locking strip for inter- hexagonal screws is put forward and the structure of the locking strip, the bending process and the forming die of the locking strip are designed and calculated in this paper. Furthermore, the fastening tool of the locking strip is designed, and the feasibility of the locking strip is verified in the experiment so as to improve the anti-loosening reliability. The locking strip for inter- hexagonal bolts can be widely applied to the locking and fastening industry application fields.
