Solid rivets are inserted into the hole and hammered flat, with the
workpiece resting on an anvil or similar. This is a much slower
process than blind riveting, and requires access to both sides of the
hole. The method has been in use for many centuries. These rivets are
usually copper or steel.

The final appearance is a flat disc or a domed head.

And countersunk - I know, we did steel riveting at school in metalwork

These rivets can be used cold, using copper, aluminium or steel, or
heated, using steel, as was usual in heavy-duty work such as traditional
ship-building. I am not sure how much it is still used. Tim's point is a
good one about countersinking. Done this way it is possible to finish
the surface, for example using a brushed or polished finish, so the
countersunk head is invisible. Did you make a bottle opener Tim? It was
a standard piece when it was still called metalwork in schools. Not PC
perhaps now? Perhaps a bit of info could be added about how
countersinking is done?
