What are the head styles of hi-shear rivets?

The head styles of hi-shear rivets include flathead and countersunk head types. Hi-shear rivets are typically designed for applications involving high shear strength, which is crucial in aviation environments, where structural integrity is paramount.

Flathead hi-shear rivets have a flat top that sits flush with the surface of the material, providing a smooth finish and minimizing aerodynamics disruption. This is essential in aviation applications as it reduces drag and adheres to design aesthetics.

Countersunk head styles are similar in that they are designed to sit flush with the surface, but they have a tapered design that allows them to blend seamlessly with the aircraft's structure. This feature is particularly important for maintaining the aerodynamic efficiency needed in flight.

Understanding these head styles is vital for selecting the appropriate rivet for specific structural applications in aircraft, where both the strength of the joint and the aerodynamics are critically assessed.
