What is the most common type of rivet used in aircraft structural repair?

The most common type of rivet used in aircraft structural repair is the solid shank rivet. Solid shank rivets are favored in aviation for their strength and reliability. They consist of a solid cylindrical shaft that is deformed (or “dimpled”) at the end to fasten materials together. This type of rivet is often used in primary structures where strength is critical, making it ideal for high-stress areas in an aircraft's frame.

These rivets provide excellent shear and tensile strength, which is essential for the structural integrity of the aircraft. When installed properly, solid shank rivets create a tight and permanent bond between components. In addition, they are often used in conjunction with various tools and procedures that ensure a consistent installation quality, contributing to the overall safety of the aircraft.

While other types of rivets, such as blind rivets, are useful in specific situations—especially where access to the back of a workpiece is limited—the solid shank rivet remains the traditional choice for critical structural components in aerospace applications due to its proven performance under various loads and conditions.
