What is the primary function of a compression riveter?

The primary function of a compression riveter is to compress rivets to a predetermined pressure. This tool is specifically designed for the process of installing rivets in a way that ensures they are securely fastened while maintaining the integrity of the material being worked on. The use of a compression riveter applies a significant amount of force to the rivet, causing it to deform and properly seat itself within the materials being joined. This compression is crucial because it ensures that the rivet creates a strong mechanical bond that can withstand various stressors encountered during the operation of an aircraft.

In the context of aerospace assembly, using a compression riveter correctly is vital for achieving the required safety and performance criteria. An improperly installed rivet can lead to structural failures, so understanding the operational purpose of the compression riveter highlights its role in maintaining quality and safety standards.

The other options focus on different tasks not relevant to the primary function of a compression riveter. They involve processes like measuring torque, creating rotational motion, or detaching components, none of which align with the main purpose of compressing rivets.
