A socket wrench is a type of wrench (spanner in British English) that inserts into a socket to turn a fastener, typically in the form of a nut or bolt.
The most prevalent form is the ratcheting socket wrench, often informally called a ratchet. A ratchet incorporates a reversible ratcheting mechanism which allows the user to pivot the tool back and forth to turn its socket instead of removing and repositioning a wrench to do so.
The basic contemporary form of socket is hexagonal, referred to as "6-point" for the pointed intersections where its six solid sided facets meet. These are attached to the driving tool via a male/female square connection fitting (called the square drive). Standard sizes of square drives around the world include 1⁄4, 3⁄8, 1⁄2, 3⁄4, 1, 1 1⁄2, 2 1⁄2 and 3 1⁄2-inch square drive sizes (a de facto international standard with no metric equivalents). This wide range of square drive sizes provides for a wide variety of socket types and sizes to suit small to very large nuts and bolts.
