This set is widely used in various areas, such as engine repair, tire replacement, and bodywork, to name just a few. Their use simplifies the process of dismantling components during repair works, such as removing wheels, engine parts, or body panels, and aids in the reassembly process, ensuring that each part is securely fastened. Different sizes and types of sockets and ratchets including metric and SAE ensure that the mechanic can work with different sizes and types of fasteners, contributing to the versatility and adaptability of these tools in automotive repair tasks.

Breaker Bars and Torque Wrenches

Breaker bars and torque wrenches are specialized tools used by auto mechanics for specific purposes in vehicle repair and maintenance. A breaker bar is a long, non-ratcheting bar that provides extra leverage to manually loosen stubborn or tightly torqued nuts and bolts. Mechanics often use breaker bars in situations where a lot of force is required, such as loosening lug nuts on wheels or other highly torqued engine components.

A torque wrench, on the other hand, is a precision tool used to tighten nuts and bolts to a specific torque value, ensuring that the fasteners are neither too loose nor too tight. This is crucial in engine assembly and other sensitive parts of a vehicle where proper torque is necessary to maintain the integrity and functionality of components. Torque wrenches allow mechanics to apply a precise level of force to fasteners, providing accuracy and consistency in the assembly process, which is essential for the reliability and safety of the vehicle.

So, in essence, breaker bars are mainly used for loosening, and torque wrenches are used for precise tightening to manufacturer specifications in various automotive repair and maintenance tasks.

Pry-Bars, Picks, Files
