As shown in Fig. 3 and Fig. 4, the anti-slip coating B is applied on the screw portion C in a vertical manner, but due to the direction problem of the screw A when screwing the bolt, it cannot be effectively and evenly distributed on the screw portion during locking. Locked.

Therefore, how to use innovative hardware design to provide a strength enough to be evenly distributed at the locking position during locking, and to achieve the best locking benefit at a lower cost, is still the current development of related industries such as making screws. It is a problem that the industry and related researchers need to continue to work hard to overcome and solve.
