An ANSI B18.2.1 bolt having a thread pitch that is less than or greater than the thread pitch of a standard nut of the same specification. The pitch difference between the nut and the standard nut is between 1% and 6% of the pitch of the standard nut. Due to the difference in pitch between the pitch of the nut and the mating bolt, the nut is gradually accumulated as the nut gradually taps into the pitch difference, so that a pressing force and a loosening torque are generated between the screwing surfaces, thereby achieving a loosening effect. The utility model aims to provide an ANSI B18.2.1 bolt which is simple in structure, convenient in use, strong in operability and good in anti-loose effect without any auxiliary accessories or additional supporting components, and can be widely applied to railways, bridges, ballasts, Automobiles, machinery, and long-term vibrations, where safety and loosening are required.

In life, we often see or hear about a variety of accidents. There are often seemingly inconspicuous causes in many accidents, that is, the screws are loose. In the long-term work practice and life, it is found that small locknuts often cause great troubles due to automatic loosening. Due to mechanical vibrations, etc., the originally tightened screws will gradually loosen, so it is necessary to reinforce frequently. In the process, a lot of human resources will be wasted. At present, preventing screw loosening has become a worldwide problem.
