Abstract: A socket wrench includes a squares solid rod which non-rotatably interfits within the squared bore of a sleeve. The squared rod has an enlarged head in which a driver releaseably seats. Both the rod and the sleeve are provided with a solid end of squared or other shape to which the attachment end of each of a series of differently sized sockets releaseably catches; and the squared rod includes a spring-biased ball detent which releaseably locks the squared rod to the receiving sleeve in its adjusted position.
