What is the purpose of using a torque wrench during assembly?

Using a torque wrench during assembly primarily serves the purpose of ensuring that bolts are tightened to the specified torque values. This is crucial because each bolt or fastener has a torque specification, which is the amount of rotational force that should be applied to it. Adhering to these specifications prevents issues such as under-tightening, which may lead to loose connections and potential failure, or over-tightening, which can strip threads or damage components.

Properly torqued fasteners also help maintain an even distribution of load and stress across the assembly, which contributes to the integrity and longevity of the joint. By using a torque wrench, technicians can achieve the necessary precision required in mechanical and structural applications, ultimately promoting safety and reliability in the assembled equipment or structure.
