A nut, also known as a nut (English: Nut), is a fixing tool with a hole in the center and a thread on the inside of the hole. Nuts are often shared with screws of the same size to fix related joints. If environmental factors such as vibration cause the nut to loosen, you can use glue or pins and other tools to further strengthen the relevant part. The nuts are mostly hexagonal, followed by squares. m3 nut
1. A nut is a nut, which is screwed together with a bolt or screw for fastening. A component that must be used in all production and manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper). ) And other major types. According to attributes, there are mainly national standards (GB), German standards (DIN), international standards (ISO), Japanese standards (JIS), American standards (ASTM/ANSI) and other standards. Among them, the national standard, the German standard, and the Japanese standard are represented by M (for example, M8, M16), while the American system and the British system are represented by fractions or # (such as 8#, 10#, 1/4, 3/8).
2. Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts ( 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, 1/4-20 nuts can only be used with 1/4-20 screw rods. Match (1/4 means that the inner diameter of the nut is approximately 0.25 inches, 20 means that there are 20 teeth in each inch). High-strength nut
