What should you do when a click-type torque wrench clicks at the set point?

• A. Stop turning the wrench
• B. Continue applying pressure
• C. Loosen the bolt slightly
• D. Check the torque setting

Answer: (A)

When a click-type torque wrench clicks at the set point, the appropriate action is to stop turning the wrench. The click is an audible signal indicating that the desired torque has been achieved. Continuing to apply pressure after hearing the click may lead to over-tightening the fastener, which can cause damage to the bolt, the surrounding materials, or compromise the integrity of the assembly. Understanding the mechanism of a click-type torque wrench is crucial. This tool is designed to provide a precise torque reading, and the click serves as a reliable feedback mechanism. Stopping immediately upon hearing the click ensures that the torque applied is exactly what is needed according to specifications. In this context, options that suggest continuing to apply pressure or loosening the bolt reflect an understanding that deviates from the purpose of the click mechanism, which is to indicate the precise moment to halt the application of torque. Checking the torque setting may also be appropriate, but it does not directly address the immediate action required at the moment the click is heard. Thus, stopping is the most effective action to take when the click occurs, ensuring that the torque specification is adhered to correctly.
