In hand riveting, what tool is used to support the manufactured head of the rivet?

In hand riveting, a rivet snap is the tool specifically designed to support the manufactured head of the rivet during the riveting process. When a rivet is driven into place, the rivet snap provides a surface that aligns with the head of the rivet, allowing for the application of force to form the tail of the rivet securely against the material being joined. This is crucial for ensuring a strong and uniform connection between the components.

The other tools mentioned serve different purposes and are not suitable for supporting the rivet head. A rivet cutter is typically used for cutting rivets to length or for trimming rivets, while a pneumatic hammer is used to impact or drive rivets but does not provide head support. An electromagnetic drill is designed for drilling holes in materials but has no function in the riveting process itself. Understanding these distinctions highlights the importance of using the correct tool for each task in aerospace assembly processes.
