What type of torque wrench produces an audible click signaling that the set torque has been reached?

The type of torque wrench that produces an audible click to signal that the set torque has been reached is the click torque wrench. This tool is designed with a mechanism that allows the user to set a specific torque value. When the applied torque reaches that predetermined setting, the wrench emits a distinct clicking sound, alerting the mechanic that they should stop applying force.

This feature helps ensure accuracy in tightening fasteners to the specified torque, which is critical in aerospace assembly where precise torque levels are essential for safety and performance. By providing an audible indication, the click torque wrench allows the user to focus on the task without having to constantly monitor a gauge or reading.

Other types of torque wrenches, such as digital indicator, pneumatic, and beam wrenches, operate differently. Digital indicator wrenches provide a numeric readout of torque applied without an audible signal, pneumatic wrenches are powered by compressed air and do not use a click mechanism, and beam torque wrenches rely on a dial or pointer to show torque but do not provide an audible alert when the target torque is reached.
