Self-Piercing Rivets

Self-piercing riveting is a high-speed mechanical fastening process for point joining sheet material, typically steels and aluminium alloys. It is a single-step technique, generally using a semi-tubular rivet to clinch the sheets in a mechanical joint. There is also a process variant which utilises solid rivets.

As the name suggests, pre-drilled holes are not required, allowing the joint to be made rapidly in one operation.
