True or False: Torque wrenches are designed to loosen stubborn bolts or nuts.

1. True

2. False

3. Only for tightening

4. Used only in automotive applications

The correct answer is: False

The assertion that torque wrenches are designed to loosen stubborn bolts or nuts is false. Torque wrenches are precision tools specifically designed to apply a predefined torque to bolts and nuts, ensuring they are tightened to the correct specification. This is important in many applications, including mechanical assemblies, where over-tightening or under-tightening can lead to failure or damage. These tools calibrate the amount of rotational force applied to a fastener, making them essential for tasks that require accuracy in tension, such as in automotive, aerospace, and construction applications. While some might attempt to use a torque wrench to loosen fasteners, that is not its intended purpose. Using a torque wrench in this way can also lead to inaccurate readings and potential damage to the tool or fastener. Thus, torque wrenches serve a specific role—applied torque during fastening—rather than as tools for loosening.
