RIVET: SOLID,CSK HD,ST (P/N 78-129) - New Surplus

The 78-129 is a solid countersunk-head steel rivet for permanent flush fastening in aircraft sheet-metal structures. This rivet maintains a smooth, aerodynamic surface where flush joints are required on exterior skins and interior panels. Installation uses a rivet gun and bucking bar to form a secure mechanical bond.

The countersunk head sits flush with the surface, eliminating protrusions that would disrupt airflow or create stress concentrations. Commonly specified in aircraft repair and assembly work per FAA AC 43.13-1B guidance and aircraft structural repair manuals.
