ABSTRACT:
A socket wrench comprises a socket head having an opening for slidably receiving a nut and a flange disposed at an opposite end of the opening and extending inwardly into the opening; a pipe having one end secured to the socket head; and a driver receptor secured to the other end of the pipe. The flange includes a central opening that is smaller than the inside diameter of the pipe and that communicates with the interior of the pipe, thereby permitting an end portion of a long bolt to extend into the interior of the pipe when a nut is screwed down along the bolt.
