This wide rivet setter is a good width for large and X-large rapid rivets and double cap rivets. This wider rivet setter is wide enough for these wider cap rivets so it will not leave a ring on the metal cap. Rivets can also be set flat without using a rivet setter by tapping them flat with a hammer that has a bit of a convex metal head. Always use a metal anvil or solid piece of steel under the rivet that is on a work surface that will not bounce.
