Basic knowledge of nut classification and principle

Nuts are parts that are closely connected to mechanical equipment. Nuts and bolts of the same specification can be joined together by internal thread. For example, the M4-P0.7 nut can only be connected to the M4-P0.7 series of bolts (for nuts, M4 means the inside diameter of the nut is about 4mm, and 0.7 means the distance between the two threads is 0.7mm); The same is true for American products, such as 1/4 -20 nuts that can only be used with 1/4 -20 screws (1/4 means that the nut has an inside diameter of approximately 0.25 "and 20 means that the nut has an inside diameter of approximately 0.25"). 20 teeth per inch).

The disc-lock nut consists of two sections, each with an interlaced CAM. Because the internal wedge design has a greater Angle of inclination than the bolt's nut Angle, the combination is tightly integrated, and when vibrations occur, the protrudes of the disc-lock LOCK nut stagger from each other, creating lifting tension for loosening.
