Technician A says that torque prevailing nuts can be reused unless damaged. Technician B says that a new cotter key should always be used. Which technician is correct?

Question

Quizplus · Accepted Answer

Technician B is correct because cotter keys (cotter pins) are designed for single use and should always be replaced with a new one after removal to ensure proper locking and safety. Torque prevailing nuts, on the other hand, are typically designed for one-time use due to their locking feature that may be compromised after initial use, making Technician A's statement incorrect.
