Gripper Socket

A high quality almost universal socket on a 3/8" square drive. By almost universal, we mean this single socket can be used on nuts or bolt heads from 6mm or 1/4"AF to 19mm or 3/4"AF, virtually irrespective of the wear and, within reason, the deformity of the hex. It will also work equally well on some square nuts as well. One tool that will take a firm grip of a multitude of sizes, almost a socket set in itself.
