What type of torque wrench requires the user to be aware of the maximum torque value?

A dial type manual torque wrench requires the user to be aware of the maximum torque value because it relies on a dial gauge that displays the torque being applied. Unlike some other torque wrenches that provide an audible or tactile indication (such as a clicking sound or a digital display), a dial type requires constant monitoring by the operator.

The user must visually observe the needle on the dial and manually stop applying torque once the desired torque value is reached. If the maximum torque value is exceeded, there is the potential for damage to the fastener or assembly. As a result, having an understanding of the maximum torque specification is crucial for effective and safe operation.

In contrast, click type manual torque wrenches provide an audible click when the set torque level is reached, while digital torque wrenches often feature a display that alerts the user. Pneumatic torque wrenches typically have built-in features to control torque and may be less dependent on user monitoring for maximum values.
