An Air Riveting Hammer is a pneumatically powered impact tool designed to install (set) solid rivets by delivering rapid, controlled hammer blows to the rivet head. It is one of the most essential tools used in aerospace manufacturing, automotive body assembly, shipbuilding, and structural metal fabrication, where strong, permanent joints are required. The tool uses compressed air to drive an internal piston back and forth, transferring repeated impacts to a rivet set (tool bit) that deforms and locks the rivet into place. Different hammer sizes and stroke energies are chosen according to rivet diameter and material hardness.
