Abstract
A socket wrench has a rotatable cylindrical body with an elongated interior channel for storing a plurality of nuts. The channel has a nut opening at a first end for receiving and removing nuts from the channel. A longitudinally slidable and axially rotatable roller grip assembly is provided on the exterior of the body. The roller grip assembly is attached to an interior backplate that moves longitudinally within the body channel. The roller grip assembly allows an operator both to urge the stored nuts toward the nut opening of the wrench, eject the nuts from the chamber, and to hold the wrench while the body is rotating.
