What are the characteristics of rivets?

Rivets are cylindrical metallic fasteners used to join materials together, typically composed of steel, aluminum, or copper. They feature a smooth shaft and a head on one end, which is deformed or "set" during installation to secure the connection. Rivets are known for their high shear and tensile strength, making them suitable for structural applications. Additionally, they provide a permanent and vibration-resistant joint, often used in construction, aerospace, and manufacturing.
