nut

Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same size can only be connected together through internal threads. For example, nuts of m4-p0.7 can only be connected with bolts of m4-p0.7 series (in nuts, the inner diameter of the M4 finger nut is about 4mm and the distance between the two thread teeth of 0.7 finger is 0.7mm). The same is true of American products. For example, the 1/4 to 20 nut can only be used with 1/4 to 20 screws (the inner diameter of the 1/4 finger nut is about 0.25 inch, 20 fingers for every inch, there are 20 teeth).
