Nut

Nut is a kind of nut, which is screwed together with bolt or screw for fastening. According to different materials, it can be divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types.
Nuts are parts that closely connect mechanical equipment. Through the inner thread, nuts and bolts of the same specifications can be connected together. 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, which is about 4mm, and 0.7 refers to the distance between two threads, which 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 the inner diameter of the nut is about 0.25 inch, 20 refers to 20 teeth in each inch).
