What is the primary objective of torquing a nut and bolt?

The primary objective of torquing a nut and bolt is to define the clamping force of the fastener. When a fastener is torqued to a specific value, it generates a predetermined amount of tension in the bolt, which creates a clamping force between the connected components. This clamping force is crucial for maintaining the integrity of the assembly, as it prevents movement or separation of the parts under various conditions, such as vibration or thermal expansion.

Adequate torque ensures that the fasteners are tight enough to hold the components together effectively, but not so tight that they become damaged or stripped. Therefore, achieving the correct torque is essential for the overall performance and safety of the assembly.
