Abstract
A method and apparatus is provided for stamping or printing identification indicia on a circular segment such as the flat portion of the head of a cap screw, bearing race, or stud end. The adjustable diameter stamp uses a plurality of segments which, when fitted together, form a cylinder or other polygonal shape which is held securely in a matching collet during the stamping operation. Variable diameter stamping is accomplished by using different sized stamping segments. Also, shims may be used to provide marking diameter adjustment. The preferred embodiment uses four wedge-shaped stamping segments.
