A type of wrench used to turn a nut or bolt. The socket is a small cylinder of high-strength chrome-vanadium steel. One end of the cylinder has either a 6-point or 12-point opening that fits the nut or bolt head. The other end has a square hole that fits the handle used to drive the socket. These drive holes are usually 1/4-inch, 3/8-inch, 1/2-inch, or 3/4-inch square, depending on the size nut the socket is designed to turn.
Ratchet handles, breakover handles, and speed handles can be used to drive the socket. Extensions of various lengths, and universal joints may be used between the socket and the drive handle to allow the socket to fit squarely on the nut and be turned by the handle.
