What is a primary purpose of using a rivet gun?

The primary purpose of using a rivet gun is to set rivets securely. Rivet guns deliver the necessary force to deform the rivet and secure the two pieces of metal together effectively. This process is essential in aircraft construction and maintenance, where structural integrity and reliable fastening are critical to the safety and performance of the aircraft.

Rivet guns work by applying high-impact energy to the rivet, allowing it to expand and fill the holes in the materials being joined. This creates a strong and permanent bond, which is crucial in maintaining the structural capabilities of an aircraft.

The other options, while related to metalworking tasks, do not align with the primary function of a rivet gun. Cutting metal sheets, drilling holes, and sanding surfaces are all processes that require different tools designed for precision and effectiveness in their respective applications, rather than the specialized task of setting rivets.
