The rivet is deformed by pounding or smashing of the tail, which makes the material flatter and usually causes the tail to be expanded by about one and a half times the size of the stem's original diameter.
When finished the tail has the appearance of a dumbbell shape completing the riveted joint.
Riveting can create either lap or butt joints with a variety of different rivet configurations, including single, double and zig-zag formations.
