What are the 4 shoulder washers used for?
The four included shoulder washers are meant to accommodate smaller screws in case the original holes on the ball plate are too large. These washers will reduce the risk of smaller screw heads stripping through the larger holes, and can be used with any of the holes on the ball plate.
