Breaker bar

The long handle on breaker bars compared to shorter wrenches allows a larger torque to be generated with the same amount of force.

A breaker bar is able to create a larger amount of rotational force compared to a standard socket wrench.

[4] Since the breaker bar creates and withstands a larger amount of torque it is often used in place of a standard socket wrench to break loose tight-fitting fasteners.

Because of its high yield strength and shock resistance, standard socket wrenches, and breaker bars are fashioned from this material.

In addition to its high yield strength, chromium-vanadium steel provides resistance to abrasion, oxidation, and corrosion making it a viable material for the production of tools.

A breaker bar creates a larger force due to the amount of torque that can be applied through a longer handle versus a shorter one.
