Nuts are divided into carbon steel, high-strength, stainless steel, plastic steel and other major types according to different materials. According to the product attributes corresponding to different national standards, they are divided into ordinary, non-standard, (old) national standard, new national standard, US, British German standard. With different sizes, the threads are not equally divided into different specifications. Generally, the national standard and the German standard are represented by M (such as M8, M16), while the American and British systems use fractions or # to represent specifications (such as 8#, 10#, 1/4, 3/8).
Nuts are parts that tightly connect mechanical equipment. They can be connected together through the inner thread, nuts and screws of the same specification. For example, M4-0.7 nuts can only be matched with M4-0.7 screws
In the nut, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be used with a 1/4-20 screw Match (1/4 means that the inner diameter of the nut is about 0.25 inches, 20 means that there are 20 teeth in each inch).
