A rivet gun, also known as a rivet hammer or a pneumatic hammer, is a tool used to drive rivets. The rivet gun strikes the rivet's factory head, the head present before riveting takes place, while a bucking bar supports the tail of the rivet on the opposite side; the energy from the gun drives the work and the rivet against the bucking bar, so the tail is compressed and work-hardened while the work is drawn tightly together and held between the rivet head and the newly formed tail. Nearly all rivet guns are pneumatically powered; those used to drive rivets in structural steel are quite large, while those used in aircraft assembly are easily held in one hand. A rivet gun differs from a plain air hammer in the precision of the driving force it applies.
