ABSTRACT:
A light-weight, low-profile socket wrench system includes a set of thin-walled sockets, each having a round peripheral surface around which a multiplicity of gear-like teeth are distributed, and a ratchet wrench having a cylindrical opening in its head in which a socket is releasably maintained, with its teeth directly engaged by teeth on a pawl, for applying rotational torque directly to the peripheral surface of the socket. Permanent magnets supported in the wrench head maintain the socket in easily releasable operational engagement with the wrench.
