Hexagonal nuts are also called hexagonal nuts. Generally, there are many types of nuts, including hexagonal nuts, round nuts, square nuts, etc. Some standards for nuts are still relatively clear. Some specifications and size standards, material requirements standards, electroplating standards, etc. are relatively clear. And different types of nuts also have different standards. Introduce the specifications and standards of nuts in detail.

The use of hexagonal nuts in cooperation with screws, bolts and screws plays the role of connecting fastening parts. Among them, the type 1 hexagonal nut is the most widely used. Class C nuts are used on machines, equipment or structures with relatively rough surfaces and low precision requirements; Class A and B nuts are used on machines, equipment or structures with relatively smooth surfaces and high precision requirements. The thickness M of the type 2 hexagonal nut is thicker, and it is mostly used in occasions where it often needs to be assembled and disassembled. The thickness M of the hexagonal thin nut is thinner, and it is mostly used in occasions where the surface space of the connected parts is limited.
