Types of nuts

Nuts are nuts, screws or screw together to tighten the role of parts, all production and manufacturing machinery must use a component according to the different material, divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types. 

Nuts are parts that closely connect mechanical equipment. Nuts and bolts of the same specification can be connected together through internal threads. For example, nuts of M4-P0.7 can only be connected with bolts of M4-P0.7 series (in nuts, the inner diameter of M4 finger nuts is about 4mm, and 0.7 refers to the distance between two thread teeth is 0.7mm).  The same is true for American products, such as 1/4-20 nuts that can only be matched with 1/4-20 screws (1/4 finger nuts have an inside diameter of approximately 0.25 inch, and 20 fingers have 20 teeth per inch).
