High Quality Content by WIKIPEDIA articles! The socket wrench includes a ratcheting mechanism that allows the nut to be tightened or loosened with a reciprocating motion, without requiring that the wrench be removed and refitted after each turn. Typically, a small lever behind the socket switches the wrench between tightening and loosening mode. The sockets are attached to the ratchet through a square fitting that contains a spring loaded ball detent mechanism to keep the sockets in place. These drive fittings come in four common sizes: 1/4 inch, 3/8 inch, 1/2 inch, and 3/4 inch (referred to as "drives", as in "3/8 drive"). Despite being denominated in inches, these are international standards and no metric counterparts exist. Larger drive sizes i.e. 3/4 inch, 1 inch and above are usually reserved for use on fasteners used on larger industrial equipment, e.g. in shipyards
