What shape can rivets come in when fastening materials together?

Rivets are versatile fasteners that can come in a variety of shapes to suit different applications and materials being joined. While round and square rivets are commonly used, there are also flat, oval, and other specially designed shapes that serve specific functions, such as improving grip or allowing for a more discrete fastening. This variety helps engineers select the most appropriate rivet shape for the mechanical requirements of a project, such as load distribution and alignment. The ability to choose from multiple shapes enhances the effectiveness of the fastening process and allows for compatibility with different connection requirements.
