A ratchet and socket combination (sometimes called a socket wrench) lets you turn a nut or bolt without repositioning the tool on the fastener — like you need to do with a wrench when there isn't enough room to turn it in a full circle. This can make the work quicker.
Ratchets have many advantages including the ability to be used in tight places, as well as being able to loosen bolts at very high torque, and re-tighten them to the same torque. As well, the variety of combinations and adaptability, makes the ratchet and socket very useful tools.
