Which tool would you use to ensure proper torque on fasteners?

Using a torque wrench is essential for ensuring the correct torque on fasteners. This tool is specifically designed to apply a precise level of torque to nuts, bolts, and screws, which is critical in mechanical assembly and maintenance. Proper torque prevents issues such as over-tightening, which can lead to damage to components or stripping threads, as well as under-tightening, which can cause loosening or failure in the assembled structure.

The torque wrench measures the amount of force applied and clicks or gives a signal when the desired torque level is reached, allowing the user to avoid exceeding the recommended specifications. This is particularly important in aviation applications where safety and structural integrity are paramount. Other tools, like hammers, screwdrivers, or drills, do not have the capability to measure torque and are not suitable for this purpose. Using those tools instead of a torque wrench could result in improper fastening that compromises the safety and performance of the aircraft.
