Nautical Term: Countersunk rivet
Definition of Countersunk rivet
A countersunk rivet is a type of rivet that is driven below the surface of the material on one or both sides. This creates a recess or indentation around the head of the rivet. By sinking the rivet below the surface, it creates a clean and seamless appearance on the outer surface of the material.
For example, when constructing a metal boat hull, countersunk rivets are often used to join the various panels and sections together. By using countersunk rivets, the finished hull has a smooth and uninterrupted outer surface, making it both aesthetically pleasing and more aerodynamically efficient.
