Do you know how many types of nuts there are?

Nuts, a fastener that complements screws, are often seen in our daily lives. However, even people who know something about machinery may feel confused when faced with the dazzling array of nut types on the market. So how many types of nuts do you know?

1. Hexagonal head nuts

The six flat sides of the hexagonal head nut illustrate its unique appearance and fastening performance. This nut is widely used in various machinery and equipment and is one of the indispensable fasteners.

(1) Definition and classification of external hexagonal nuts

The external hexagonal nut has a hexagonal shape and is mainly used with fasteners such as bolts and screws to connect and fasten. According to the nominal thickness, external hexagonal nuts can be divided into three categories: type I, type II and thin. For nuts above grade 8, they are divided into type I and type II, among which type I nuts are further divided into three grades: A, B, and C.

(2) Applications

Grade A and B nuts are often used in machines, equipment and structures with small surface roughness and extremely high precision requirements due to their high precision requirements. Grade C nuts, on the other hand, have lower precision requirements and are suitable for machines, equipment or structures with rougher surfaces. In addition, Type II hexagonal nuts, due to their thicker thickness, are particularly suitable for occasions where assembly and disassembly are frequently required.

(3) Application of external hexagonal nuts

The unique hexagonal shape of external hexagonal nuts allows them to play their unique advantages in many applications. They can provide a stable tightening effect in situations where high-strength tightening is required, thereby ensuring the stability of machines, equipment and structures. At the same time, their easy-to-operate characteristics also make the assembly and disassembly process simple and quick, thereby improving work efficiency.

2. Application of square nuts

Square nuts, with their square shape, show their unique value in specific applications. Their design features allow them to provide a stable tightening effect in situations where high-strength tightening is required, thereby ensuring the stability of machines, equipment and structures. In addition, their unique shape also makes it easy to deal with during the assembly and disassembly process, further improving work efficiency.

(1) Definition and characteristics of square nuts

Square nuts, due to their unique square shape, are also called square nuts or square nuts. This type of nut belongs to the category of welding nuts. Its working principle is to melt the metal material at high temperature and then weld it between two products to achieve the effect of tightening.

(2) Application occasions

The tightening effect of square nuts is very good and it is not easy to loosen. Therefore, they are widely used in many industries, including road traffic and home building materials. Its wide range of applications almost meets the needs of fasteners in all fields and has become an indispensable part of mechanical fasteners.

3. Flange nuts

(1) Definition and characteristics of flange nuts

Flange nuts, also known as washer nuts, have the same size specifications as standard hexagonal nuts. Its gasket and nut are designed as one piece, and the bottom is equipped with anti-slip teeth. This design not only increases the surface area contact between the nut and the workpiece, but also improves its anti-loosening performance. Compared with the traditional nut and washer combination, it is more advantageous.

(2) Application occasions

Flange nuts are widely used to connect two pipes or pipes and equipment. With its excellent sealing performance, they are often used for workpieces that need to increase the contact surface of the nut to ensure the stability and airtightness of the connection. It can withstand high pressure and high temperature environments, effectively preventing leakage and loosening.
