A ratchet wrench is one of the most common types of socket wrench. It has a ratcheting mechanism that allows the nut to be loosened or tightened using a reciprocating motion without the wrench needing to be removed after each turn. Most of the time, ratchet wrenches have a small lever located on the ratchet head that enables the wrench to be switched between tightening and loosening modes.
There are different drive fittings typically ¼ inch, 3/8 inch, ½ inch and ¾ inch. The drive fittings can vary depending on the brand of the wrench. Some brands offer more drive sizes. Ratchet wrenches can be expensive, depending on the brand and design.
