ABSTRACT:
The stud holder has in the interior of the supply passage of the stud holder proximal to the workpiece side of the clamp jaws, a circular groove for engaging and holding a headlike enlargement of the stud in a plane perpendicular to the axis of the clamp jaws. The supply passage is constricted conically, narrowing in the feed direction of the stud, upstream of the circular groove with respect to feed of studs at least adjacent the clamp jaws. The jaws are expandable against a spring tensioned under influence of the stud as the stud is fed.
