Type of nut

Nuts are parts that closely connect mechanical equipment. 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 threads is 0.7mm); The same is true for American products. For example, 1/4-20 nuts can only be matched with 1/4-20 screws (1/4 refers to nuts with an internal diameter of about 0.25 inches, and 20 refers to 20 teeth in each inch).
