Which fastener is specifically mentioned for installation with a pneumatically powered gun?

The rivet is specifically mentioned for installation with a pneumatically powered gun because of its design and the mechanics involved in the riveting process. Rivets are commonly used in aerospace assembly due to their ability to create strong, permanent joints between materials, especially in applications involving metals.

The use of a pneumatically powered gun, or riveter, facilitates the rapid and efficient installation of rivets, making it a preferred method in the aerospace industry where speed and precision are critical. This apparatus delivers the necessary force to upset the rivet’s tail, creating a secure connection that is often used in airframe construction.

Though nuts, washers, and bolts are essential components in assembly, they typically do not require the same pneumatic equipment for installation. Nuts and bolts are usually torqued by hand tools or electric wrenches rather than being driven in using pneumatic systems. Washers simply act as spacers or load distributors and do not undergo a fastening process that would necessitate a specialized gun.
