Nylon Shoulder Washer, Hillman, White 0.562 in x 0.260 in

Finishing washers are designed to accommodate the head of a countersunk screw in order to provide a finished appearance. Shoulder washers are thicker compared to their outer diameter than usual, offering greater strength and insulation. Their non-abrasive and low surface friction characteristics make shoulder washers useful as glides, bumpers, feet and spacers.
