Abstract

A method of making a recess in a drive socket and the like includes forming a groove to extend along a face of an elongated drive opening in a metal workpiece from one end of its drive opening, moving material from the surface of the groove to increase its depth from its outer end along only a portion of its length and gathering the material so moved from the groove surface to form a ledge between ends of the groove, whereby a recess is defined by the groove extending beyond the ledge. In addition, a female drive device for socket wrenches and the like is disclosed having an elongated drive opening, a groove longitudinally extending from one end of the drive opening along a face of the drive opening, and a ledge between ends of the groove. The ledge protrudes radially inwardly such that a recess is defined by the groove extending beyond the ledge for retaining a male drive member.
