We still see and use rivet nuts in our daily lives, so how much do you know about rivet nuts? The purpose of the rivet nut: If the nut of the product needs to be installed outside and the internal space is small, the indenter of the sub-rivet machine cannot enter the rivet, and the sprouting method cannot meet the requirements. If the strength is required, riveting and expansion riveting are not feasible. Blind riveting must be used. Suitable for the fastening field of plates and tubes (0.5MM-6MM) of various thicknesses. It can be riveted by pneumatic or manual rivet gun at one time, which is convenient and firm. Instead of traditional welding nuts, it can make up for the shortcomings of thin metal plates, thin tubes, easy welding, and non-smooth welding nuts. In addition, there are many types of rivet nuts, one of which is called countersunk head rivet nut .
The countersunk head rivet nut is called "the gospel of the thin plate connection process" abroad. It changes the old method of traditional craftsmanship. When installing parts on a thin plate, there is no need to knock internal threads and weld nuts. Strong, beautiful and convenient. , Fast function, can be widely used in the assembly of electrical and light industrial products such as *, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decorations, etc.
The countersunk head rivet nut is riveted into the chamfered thin plate hole, and its top surface is flush with the plate surface after installation. As the name suggests, the outer diameter and thickness of the head of the small countersunk head rivet nut is smaller than the (large) countersunk head rivet nut. If the metal plate is relatively thin and the chamfer is small, only small countersunk head rivet nuts can be used.
Therefore, the use of countersunk head rivet nuts is still very much.
