I have some of those for my Maytag.  25 years ago when I worked in automotive industry, we used those little caps on the screw studs that were molded into the backs of the Ford Explorer/Ford Aerostar windows to keep from scratching the black trim while they were in the racks awaiting placement in the vehicles.  I could get them by the handful off the floor as they were being swept up at the end of the day.  They were blue, but my mother didn't care.  I super glued them in her Kenmore and it was all set.
