As mentioned earlier, normal threads and MJ threads will be used in parallel in the aviation industry for a considerable period of time. Therefore, the implementation of the “common thread” with the new standard, to complete the old thread tolerance to ISO thread tolerance system transition is one of the important tasks we face. In accordance with the requirements of the State Administration of Standards, the standard C from 1983 to January 1 is implemented throughout the entire territory. As the new standard rigorous structure, the concept of clear, wide range of applications, its implementation is bound to improve the quality of our products, rectify and solve the problem
