Basic Information of Hex Nuts

Hexagon nut is used in conjunction with bolts and screws to connect and fasten parts. Among them, I-type hexagon nuts are the most widely used, C-grade nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; A-grade and B-grade nuts are used for machines with relatively smooth surfaces and high precision requirements. , Equipment or structure. The thickness m of the type II hexagon nut is thicker, and it is mostly used in occasions that often require assembly and disassembly. The thickness m of the hexagonal thin nut is relatively thin, and it is mostly used in occasions where the surface space of the connected parts is restricted.

Nuts are fasteners that have internal threads and are used in conjunction with bolts, and are mechanical parts that have internal threads and are used in conjunction with screws to transmit motion or power. (Guide: Cold heading and processing of threaded fasteners)

A nut is a nut, a part that is screwed together with a bolt or screw for fastening, an original part that all production and manufacturing machinery must use. There are many types of nuts, we commonly have national standards, British standards, and the United States According to the different materials, the nuts are divided into carbon steel, high-strength, stainless steel, plastic steel and other major types. According to the product attributes corresponding to different national standards, they are divided into ordinary, non-standard, (old) national standard, and 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 (e.g. M8, M16), while the U.S. and British systems use fractions or # to represent specifications (such as 8#, 10#, 1/4, 3 /8) Fasteners, 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, and 20 means that there are 20 teeth in each inch).
