1. A stainless steel nut is a stainless steel nut, a part that is screwed together with a bolt or screw for fastening. It is an original part that all production machinery must use. There are many types of nuts. Our common ones are the national standard and the British standard. American standard and Japanese standard nuts. 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 standards, New national standard, American system, British system, German standard. The size is different, and the thread is divided into different specifications. Generally, the national standard and the German standard are represented by M (such as M8, M16), and the American system and the British system are represented by fractions or # (such as 8#, 10#, 1/4, 3 /8) Fastener
2. Nuts are parts that tightly connect mechanical equipment. They can be connected together through internal threads, nuts of the same specification and stainless steel screws. 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, 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 matched with a 1/4-20 screw (1/ The inner diameter of the 4-finger nut is approximately 0.25 inches, and the 20-finger nut has 20 teeth per inch).
