Thanks to Tracy I remember the solution .

Small"O" Ring, 3/16" ID with smallest Rubber diameter available . (Very small Rubber diameter, Preferably less than 1/16")

Obtain at most any Auto Parts Distributor ( NAPA, AUTO ZONE, or the like .)Probably $.25 or so each.

Until you find these try Wrapping 1 or 2 turns of a small rubber band around the screw before screwing it down snug, then with a razor blade or similar blade cut off excess and tighten the screw. Experiment to find what works best.
