In addition, in the prior art, rivets are also used to riveted screws on metal plates. The rivets are nail-shaped objects with a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference. When using rivets, it is necessary to set moderately sized positioning holes in the corresponding positions of the two metal plates, and the rivets directly penetrate into the positioning holes and then riveted. Because this riveting method does not require welding, it will leave a hole on the back of the metal plate. Therefore, in the prior art, the surfaces of the two metal plates after riveting are covered with a layer of smooth metal skin to cover the riveting marks, which will also increase the overall cost, including metal The cost of the skin and the increase in the manufacturing process, while the riveting process is limited, the connection between all metal plates cannot be universal.

At present, the nut is used as the main body through the riveting connection with the gasket, which is more and more widely used in the industrial field, especially the automobile industry. The gasket connected with the nut has two types: spring gasket and flat gasket. After the nut is tightened, the washer gives the nut an elastic force, which is pressed against the nut to make it not easy to fall off; and the function of the flat washer is to increase the contact area between the nut and the coupling, increase the friction force, reduce the pressure per unit area and protect the surface of the connected parts. Not damaged, stop the nut from loosening. Therefore, gaskets have a wide range of applications in the field of fastening connections, and it is more and more important to improve production efficiency, reduce production costs, and meet growing demands.

Hexagon nuts are divided into three types: I type, II type and thin type according to the nominal thickness. Nuts above grade 8 are divided into two types: type 1 and type II. Type I hexagon nuts are the most widely used. Type 1 nuts are divided into three grades: A, B, and C. Among them, grade A and grade B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements. Class C nuts are used on machines, equipment or structures with rough surfaces and low precision requirements.
