Rivet: In riveting, the riveted parts are connected by their own deformation or interference.

There are many types of rivets, and they are informal.

According to the form of force, rivets can be divided into three categories: shear rivets, pull rivets and shear rivets.

Commonly used are semi-round head, flat head, countersunk head rivets, blind rivets, hollow rivets, and semi-hollow rivets. These are usually connected to the riveted parts by their own deformation. (Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for larger ones.) But there are exceptions. For example, the nameplate on the three-ring lock is riveted by the interference between the rivet and the lock body hole.

In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod.

Half round head rivets: mainly used for riveting occasions with large lateral loads, and are widely used.

Flat cone head rivets: Due to the hypertrophy of the nail head and corrosion resistance, it is often used in riveting occasions with strong corrosion such as ship hulls and boiler water tanks.

Countersunk head, 1200 countersunk head rivets: mainly used for riveting occasions where the surface must be smooth and the load is not large.

Half countersunk head and 1200 half countersunk head rivets are mainly used for riveting occasions where the surface must be smooth and the load is not large.

Flat head rivets: used for riveting occasions with general load.

Flat head and flat head rivets: mainly used for riveting of metal sheets or non-metallic materials such as leather, canvas, and wood. The large flat head rivets are mainly used for riveting of non-metallic materials.

Semi-hollow rivet: that is, the cylindrical part of the rivet is processed into a hollow, which is mainly used for riveting occasions with small load.
