Identify one common tool used in heavy equipment maintenance.

A torque wrench is a common tool in heavy equipment maintenance because it provides precise control over the amount of torque applied when tightening or loosening fasteners. This is critical in heavy equipment applications where proper torque specifications must be adhered to in order to ensure structural integrity and safe operation.

Using a torque wrench helps prevent over-tightening or under-tightening of bolts, which can lead to equipment failure, safety hazards, or costly repairs. In heavy machinery, where components are subjected to significant stress and load, maintaining the correct torque settings is vital for reliable performance and longevity of the equipment.

While other tools like a regular wrench, screwdriver, and pry bar are also used in various maintenance tasks, they do not provide the specialized control over torque that a torque wrench does, making it uniquely essential for ensuring the compliance with manufacturer's specifications and maintaining safety standards in heavy equipment maintenance.
