Rivets consist of tough steel (340 MPa), copper, brass and aluminium.
- Button head rivets:
They are used in components, where the projecting head does not disturb and are especially suitable for fixed and close joints, because a strong clamping effect is achieved by them.

- Countersunk-head rivet:
This is used in components or parts the surfaces of which must not become uneven by projecting rivet heads; it is not suitable for highly stressed connections.
Figure 4 - Countersunk-head rivet
- Oval head countersunk rivet:
They are used for such parts where the surface is rough and uneven and where no special demands are made on the quality of the surface or - on the contrary - an uneven surface shall be achieved (gangways, steel stairs - nonskid property).

- Boiler construction rivet:
A button head rivet with conical shank, which can be easily put into not quite accurately aligned bore holes. This rivet is used in the construction of pressure vessels and boilers. By caulking the plate edges and rivet heads, close and fixed connections are achieved.

- Explosive rivets:
These are used, if the components are accessible only from one side (light metal construction, aircraft manufacture). The explosive charge is electrically ignited thus widening the rivet shank.

- Belt rivet:
The belt rivet is used for connecting soft materials such as leather, rubber, felt.

- Hollow civet or tubular rivet:
This kind of rivet is used to connect delicate materials - the hammering of the rivet head requires only little force.

- Pin:
Components used in precision mechanics are sometimes equipped with a pin the projecting end of which can be worked like the shank of a rivet.
