What is the dimension for the height of the shop head of an AN470AD4-4 rivet?

The dimension for the height of the shop head of an AN470AD4-4 rivet is indeed defined as .0625 inches. This specific height is prescribed in the specifications set forth by the FAA as well as industry standards for rivets, which are typically documented in military standards or related aerospace documents.

In the context of riveting, the shop head height is crucial as it impacts the rivet's ability to properly secure the components of an aircraft structure. A shop head that is too high or too low may indicate improper installation, which could compromise the structural integrity of the joint.

Understanding the correct height helps ensure that all rivets are installed to meet the necessary strength requirements and comply with the relevant standards. Accurate measurements are fundamental for maintaining safety and structural soundness in aviation applications.
