Abstract
A fastener and method of manufacturing a threaded fastener with a tool-receiving recess in the fastener head are provided including a gauging indicator for indicating whether the recess is properly formed to meet standards. The gauging indicator is preferably in the form of a protrusion of a predetermined size on the fastener head which changes when the punch forming the recess becomes worn or broken. In this instance, the protrusion will be reduced in size as the material of the protrusion is displaced into the fastener head and other material of the fastener head is pushed into the areas of wear or breakage on the punch. Accordingly, the size of the gauging indicator provides an indication of whether the recess is meeting standards.
