Abstract
A circumferential bead for preventing pin rollover is disposed on a retainer insert mounted in the shell of a stud gripper socket and spaced from the inner surface of the shell. The shell has at least one cam surface on its inner surface and there are roller pins disposed for rolling motion on each cam surface between the cam surface and the retainer insert. Each roller pin includes a circumferential retainer groove; the circumferential bead on the retainer insert engages the grooves on the pins; the bead has a curved contour associated with each cam surface for defining a gap which, intermediate the ends of the cam surface, is at least as wide as the pin diameter less the groove depth to permit the pin to freely roll along the associated cam surface, and which is less than the pin diameter to prevent the pin from falling out of of the shell, and which gap at the ends of the cam surface is narrower than the diameter of the pin less the depth of the groove to pinch the groove and prevent the pin from rolling beyond the ends of its associated cam surface.
