Screw Sockets

Screw sockets are used to fasten and unfasten screws and bolts with tools like torque wrenches, ratchets and swivel handles. A screw socket attaches to the hand tool at one end (usually via its square drive) and the other end fixes into the middle of the fastener, so that it can be tightened or untightened like it would be if done with a screwdriver.
