The classification of rivets can be carried out from multiple angles, and the following are some of the main classification methods:
First, classification by shape
Flat head rivet: used for riveting under general load.
Half round head rivet: mainly used for riveting with large lateral load, the most widely used.
Countersunk head rivets: mainly used for riveting occasions where the surface needs to be smooth and the load is not large.
Half round countersunk head rivet: combining the characteristics of half round head and countersunk head rivet, suitable for specific occasions.
Tubular hollow rivet: Used for non-metallic materials without load riveting occasions.
Other special shape rivets: such as fan rivets, tree rivets, etc., designed according to specific application requirements.
Second, classification by use
Boiler rivets: For the riveting needs of specific equipment such as boilers.
Steel structure rivets: rivets specially used for steel structure connections.
Band rivet: May refer to a rivet with a specific band structure for a specific occasion.
Plate rivets: mainly used for riveting machines, equipment and other nameplates.
Core pulling rivets: a class of single rivet riveting, especially suitable for the inconvenience the ordinary rivet riveting occasions, such as buildings, cars, ships, aircraft, machines, electrical appliances, furniture and other products.
Core rivet: Another type of single riveted rivet, using a hammer and other objects to hit the core on one side to complete the riveting operation, especially suitable for small Spaces or can not use the riveting gun environment.
Third, by material classification
Steel rivets: made of steel, high strength, widely used.
Copper rivets: made of copper, with good electrical conductivity and corrosion resistance, suitable for specific occasions.
Aluminum rivet: made of aluminum or aluminum alloy, light weight and corrosion resistance, is suitable for the need to lose weight.
Plastic rivets, such as R type plastic rivets, consists of two parts, plastic nail and the female buckle, do not need to use tools when installation, especially suitable for light, connection of brittle materials.
Fourth, other special categories
Insert rivet: divided into two parts, the thicker part of the cap rod body has a hole in the center, and the thinner part of the cap rod body is interference fit. When riveting, drive the thin rod into the thick rod.
In summary, rivets are classified in various ways, and can be divided into various types according to different standards such as shape, use, and material. These different types of rivets have their own characteristics and application occasions, and can meet the needs of different industries and application fields.
