Abstract

A light-weight, low-profile socket wrench system includes a set of cylindrical thin-walled sockets, each having a through axial opening sufficiently large to allow a bolt engaged by a nut of a size corresponding to that of the nut-receiving opening to pass through the axial opening and extend beyond the nut, and a ratchet wrench releasably engageable with the socket for applying rotational torque directly to a peripheral surface of the socket. In a preferred embodiment, the socket has a round peripheral surface around which a multiplicity of teeth are distributed, and the head of the ratchet wrench has a circular cylindrical opening in which the socket is releasably maintained with its teeth directly engaged by teeth on a pawl.
