You can rivet a wide range of materials to one another e.g. a metal bracket to a tool box, a clip to a leather belt using a reinforcing washer, pipe clips to car bodywork, catches on suitacases, replace a nut & bolt with a pop rivet etc.
I used mine to replace the fat tray rails on my BBQ that had rusted away. A very useful tool to have in your workshop. Various rivet lengths/ diameters/ materials are available.
