Abstract
A stacked plurality of snap rings adhesibly retained by varnish coating, or other bonding method applied to the rings. Internal or external circular or C-shaped snap rings typically have retainer ring holes and in this invention the holes in adjacent rings in the stack are misaligned. Snap ring pliers or automated equipment can be inserted into the retainer ring holes of the endmost snap ring fastened at the top of the stack, with the tips of the pins penetrating only through the holes in the topmost ring, due to their misalignment, with the topmost ring being removed by movement of the pins relative to each other, thereby facilitating efficient dispensing of one snap ring at a time.
