The purpose of  anti-loosening of stud bolt connection In actual work, the external load has a  vibration, change, high-temperature creep of the material, etc., which will  reduce the friction. The positive pressure in the thread pair disappears at a  certain moment and the friction is zero, which makes the thread connection lose,  If repeated action, the threaded connection will loosen and fail. Therefore, it  is necessary to prevent loosening, otherwise, it will affect normal work and  cause accidents.
