What is a "breaker bar"?
A breaker bar is a long, heavy-duty tool used to apply extra force when loosening tight or stuck bolts, nuts, or fasteners. It is essentially a long handle, often made of steel, designed to fit over a socket wrench or impact wrench to extend its length, providing more leverage. The additional length allows the user to generate more power, making it easier to break free stubborn fasteners. Breaker bars are commonly used in automotive repair, construction, and other heavy-duty tasks where high force is needed to loosen fasteners.
