These rivets are inserted into pre-drilled countersunk holes and installed by pulling the mandrel to expand the rivet body, which securely joins two pieces of material together. After installation, the mandrel snaps off, leaving the rivet set in place with a flush head. This flush finish is beneficial for reducing aerodynamic drag on surfaces such as aircraft exteriors and preventing the rivet from catching on other components.
Countersunk pop rivets are commonly used in aerospace, automotive, and industrial applications where vibration resistance and a permanent hold are required. They are available in various materials including aluminum, steel, and stainless steel to suit different environmental conditions and strength requirements. The flush finish also makes them suitable for joining sheet metal, frames, and panels where a smooth surface is necessary.
