What is the solid part of a rivet squeeze called?

In the context of rivets, the solid part that is compressed during a riveting process is referred to as the yoke. The yoke is an essential component of the riveting tool that holds the rivet in place and applies the necessary force to squeeze the rivet, creating a permanent joint between metal parts. The operation involves transferring the compressive force through the yoke onto the rivet, leading to the formation of a strong, sealed connection.

The body of the rivet refers to the entire cylindrical portion of the rivet, and while it is involved in the process, it is not the specific part that applies compression. Similarly, the terms "base" and "frame" do not pertain to the solid part of a rivet squeeze. Understanding the role of the yoke is crucial in mastering riveting techniques and ensuring the integrity of assembled structures in aerospace applications.
