Type of nut

Nuts are the parts that connect the mechanical equipment closely. Only nuts and bolts of the same specification can be connected together through the inner thread. For example, m4-p0.7 nuts can only be connected with m4-p0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, 0.7 refers to the distance between the two thread threads is 0.7mm); the same is true for American products, such as 1 / 4-20 nuts can only be connected with 1 /4-20 screws (1 / 4 finger nut is about 0.25 inch in inner diameter, 20 finger nuts have 20 teeth in each inch).
