The ratchet is a wrench with a click mechanism, manual, cordless or pneumatic, that tightens and loosens nuts and bolts using sockets fitted to the square drive.
What it is for
Used for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Fit the socket of the exact size onto the square drive and select the direction of rotation with the selector. Work with the socket pushed fully onto the nut. With cordless or pneumatic models, run the nut down and finish tightening by hand, or with a torque wrench if a precise torque is required; pneumatic models connect to compressed air with the quick coupling and are lubricated from time to time. Do not extend the handle with tubes to force seized nuts.
