Breaker Bars
Breaker bars, also known as power bars, feature a long nonratcheting bar that is used to break loose overtightened fasteners using sockets and socket bits. To turn a fastener with a nonratcheting bar, the tool must be removed from the fastening and repositioned. When compared to a standard-length ratchet, the extended handle allows the same amount of effort to generate higher torque. Breaker bars are used in conjunction with sockets and socket bits to rotate fasteners during installation (tightening) or removal (removal) (loosen).
