Which two configurations are the most common for rivet squeezes?

Rivet squeezers are important tools in aerospace assembly, specifically for setting rivets in various applications. The most common configurations for rivet squeezes are the alligator squeeze and the C squeeze.

The alligator squeeze design typically features two jaws that close like an alligator's mouth, allowing for even pressure distribution across the rivet head. This mechanism is particularly effective for larger rivets or areas where the application of high force is required in a confined space.

The C squeeze, characterized by a frame shaped like the letter "C," provides versatility in reaching different angles and crowded areas on an assembly. It is particularly useful when working with thicker materials or in environments where maneuverability is limited.

Both configurations enhance not just the efficiency of the riveting process but also the quality and integrity of the rivet installation, which is critical in aerospace applications where reliability and safety are paramount. This makes them the most prevalent choices for mechanics in the field.
