A breaker bar is a long non-ratcheting bar that is used with socket wrench style sockets. Breaker bars are used to 'break loose' very tight fasteners because their additional length allows the same amount of force to generate significantly more torque than a standard length socket wrench. The use of a breaker bar also prevents damage to the ratcheting mechanism of a socket wrench. Often, after the first 1/2 turn of a fastener, the fastener is then loose enough to be turned with a socket wrench.
An improvised bar can be made with a length of metal pipe that has a wrench inserted into one end. This (pipe) device is often called a cheater bar.
Breaker bars are used to remove lug nuts as they are applied with great torque by an impact wrench. Breaker bars are used for roadside tire replacement to offer the driver the leverage needed to loosen the bolts.
Famous quotes containing the word bar:
“Even the most incompetent English actor, coming on the stage briefly to announce the presence below of Lord and Lady Ditherege, gives forth a sound so soft and dulcet as almost to be a bar of music. But sometimes that is all there is. The words are lost in the graceful sweep of the notes.”
—Robert Benchley (18891945)
