Extended data
Nuts are nuts that are screwed together with bolts or screws to play a fastening role. According to the different materials, all components that must be used in manufacturing machinery are divided into carbon steel, stainless steel, non-ferrous metals (such as copper) and so on.
Nuts are closely connected parts of mechanical equipment, and nuts and bolts of the same specification can only be connected together through internal threads.
For example, the nut of M4-P0.7 can only be connected with the bolts of M4-P0.7 series (in the nut, M4 means the inner diameter of the nut is about 4mm, and 0.7 means the distance between two thread teeth is 0.7mm).
So are American products. For example, the nut of 1/4-20 can only be matched with the screw of 1/4-20 (1/4 means that the inner diameter of the nut is about 0.25 inch, and 20 means that there are 20 teeth per inch).
