When should you use a torque wrench while installing a threaded fastener?

Using a torque wrench every time when installing a threaded fastener is essential for ensuring the proper clamping force and securing components accurately. A torque wrench allows the user to apply a specific amount of torque to the fastener, which is critical for achieving the manufacturer's specifications and preventing common issues associated with improper tightening, such as thread stripping, bolt failure, or uneven load distribution.

Consistent use of a torque wrench helps maintain the integrity of the assembly, as different fasteners require specific torque settings based on their size, material, and application. Using the correct torque ensures that the fastener is neither too loose nor over-tightened, both of which can lead to mechanical failure. In environments where safety and reliability are critical, such as automotive or aerospace applications, the importance of adhering to torque specifications cannot be overstated.

While large fasteners may seem to require more attention, it is not just their size that dictates the need for a torque wrench. The necessity for proper torque applies universally to all fasteners, regardless of their size. The idea of using a torque wrench only occasionally or on special occasions downplays the importance of torque management as a standard practice in mechanical assembly, which can lead to inconsistent results and potential failure, highlighting why using it consistently is the
