no those are called clecos. They hold the metal in place while you install fasteners or weld it in place. You drill a hole in two or more pieces of metal and put a cleco in the hole to keep it all from getting mis-aligned, until you get the two or more pieces bonded together.
rivets are fasteners that get shot and bucked, or you can stick a pull rivet in it and pull it with a gun.
yeah, i knew it was something in that vicinty
