FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

Question: 1 / 1030

When is the full shear strength of an MS20470D rivet obtained?

Immediately after installation

After a period of age hardening

The full shear strength of an MS20470D rivet is obtained after a period of age hardening. Age hardening involves a process where the material is allowed to sit at room temperature for a certain amount of time to reach its maximum strength. In the case of rivets, this means that their full shear strength is achieved after this age hardening process. The other options are incorrect because the rivet's maximum shear strength is not obtained immediately after installation, once the rivet is painted, or after a stress test is applied.
