What is a common application for measuring torque in aviation mechanics?

In aviation mechanics, the primary reason for measuring torque is to ensure proper fastener tightness. Torque measurement is critical because fasteners, such as bolts and screws, need to be tightened to specific values to maintain integrity and safety in aircraft structures and systems. If fasteners are over-tightened, they can strip threads or lead to fatigue failure, while under-tightened fasteners can loosen over time, resulting in critical structural failures.

This practice is essential during assembly, maintenance, and inspections, as many components endure dynamic loads, vibrations, and temperature changes. Proper torque application helps guarantee that critical components remain securely fastened under operational conditions, thus contributing to overall aircraft safety and performance.
