The wrench is a hand tool that is made for the tightening or for the loosening of bolts, nuts or anything that needs to be turned. In England, the wrench is also called a spanner and it generally works as a lever. Usually the wrench is pulled at a right angle to the axis of the lever action, bolt or nut. There are some wrenches that even have mouths fitted to them so that they can be tightened around the objects that need to be turned. The notches that are at the mouth are meant for gripping and when the wrench is pulled at the right angle to the axes of the lever, the nut or the bolt the objects that need to be tightened fit well into place.

When you are using your air ratchet wrench you should check into the cubic feet requirements of your wrench so that you can lower than the cubic feet per minute requirements of your compressor. The cubic feet per minute also mean CFM and when you buy an air ratchet wrench check into the CFM specifications.
