  . A nut is a nut, which is screwed together with a bolt or screw to fasten parts. It is an original part for all manufacturing machinery. Nuts are of various kinds. We often have nuts with national standard, British standard, American standard and Japanese standard. Nuts are divided into carbon steel, high strength, stainless steel, plastic steel and other major types according to the different materials. According to the product attributes corresponding to the different national standard numbers are divided into ordinary, non-standard, (old) national standard, new national standard, American system, British system, German standard. Different sizes, threads are divided into different specifications. Generally, national and German standards are expressed by M (e.g. M8 and M16), while American and British standards are expressed by fractions or (e.g. 8, 10, 1/4 and 3/8).

  2. Nuts are parts that are tightly connected with mechanical equipment. Only through internal threads, nuts and screws of the same specification can they be joined together. For example, M4-0.7 nuts can only be matched with M4-0.7 nuts (in nuts, the inner diameter of M4 nuts is about 4mm, and the distance between 0.7 fingers and two threads is 0.7mm). Similarly, for example, 1/4-20 nuts can only be matched with 1/4-20 nuts (1/4 finger nuts have an inner diameter of about 0.25 inches, 20 fingers have 20 teeth per inch).
