Abstract
A friction clutch hand tool in the style of a socket wrench for tightening and loosening common mechanical fasteners. Socket may be received from either side into a cylindrical opening through the wrench head. Once received inside the head, socket is gripped by rollers held captive within notches provided in cylindrical wall of opening in wrench head. Rollers grip outside surface of socket directly. Rotation of head relative to socket causes rollers to roll up ramps out of notches and wedge tight against socket, thereby simultaneously imparting torsion to fastener while clamping socket down on fastener. Socket may be assembled around fastener from multiple interlocking pieces. Socket may also be hollow.
