What tool is typically used to tighten bolts on boiler components?

A torque wrench is commonly used to tighten bolts on boiler components because it allows the operator to apply a specific amount of torque to the fasteners. This is crucial in settings like boilers where components must be secured to very specific standards to ensure safety and reliability.

Using a torque wrench helps to prevent over-tightening, which can lead to damage or failure of components, and under-tightening, which can compromise the integrity of connections. The ability to set a target torque level is particularly valuable in high-stress environments, where maintaining precise mechanical specifications is essential for operational success.

While other tools like a socket wrench and impact driver are useful for various applications, they do not provide the same level of precision in torque application that a torque wrench does, making it the appropriate choice for this specific task.
