    A breaker bar is able to create a larger amount of rotational force compared to a standard socket wrench. A standard breaker bar is strong enough to allow the user to apply up to 2,500 pound-feet (3,400 N⋅m) of torque without breaking the bar. [3] A high-end 1/2" socket wrench can withstand a maximum of 500 pound-feet (680 N⋅m) of torque. [4]
