A socket wrench device, having a shank, a plurality of socket pieces to give optionality of size, a retainer component adjacent the outer end of the shank, and with an abutment adjacent the inner end of the shank, the arrangement providing the feature that all the socket pieces which are inwardly of the outermost socket piece transmit the axial force from the abutment and sustain the reaction force form the work object, thus assuring that socket pieces unused for applying the torque work-effort to the work object must be kept on the shank for ready availability for the next use of the device, and permitting the outer retainer component to be conveniently weak for easy loading of sockets onto the shank since it need only be strong enough to retain sockets against falling off the end of the shank. Different size socket at each end of each socket provide maximum size-differences for optionality of use.
