Nut Type

Nuts are parts that tightly connect mechanical equipment, and can only be connected together with nuts and bolts of the same specification through the inner thread. For example, M4-P0.7 nuts can only be connected to M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut being approximately 4mm, and 0.7 refers to the distance between the two thread teeth being 0.7mm); The same applies to American products, such as 1/4-20 nuts that can only be paired with 1/4-20 screws (1/4 refers to a nut with an inner diameter of approximately 0.25 inches, and 20 refers to 20 teeth per inch).
