Nuts are parts that tightly connect mechanical equipment. They can be connected together by internal threads, nuts and bolts of the same specification. For example, nuts M4-P0.7 can only be connected with bolts of M4-P0.7 series (in nut In the M4, the inner diameter of the nut is approximately 4mm, and the 0.7 refers to the distance between the two thread teeth is 0.7mm); the same applies to the US product, for example, the 1/4-20 nut can only be used with the 1/4-20 screw ( The 1/4 finger nut has an inner diameter of approximately 0.25 inches and 20 fingers have 20 teeth per inch.
