The nut is a part that closely connects the mechanical equipment. Through the inner thread, nuts and bolts of the same specifications can be connected together. For example, the nut of M4-P0.7 can only be connected with bolts of M4-P0.7 series (in the nut, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two thread teeth is 0.7mm). American products are the same, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw (the inside diameter of the 1/4 finger nut is about 0.25 inch, 20 fingers per inch, there are 20 teeth).
