Choose these washers for their adherence to strict military standards for material and construction. Teeth on the outside edge of the washer bite into the screw head and joint for a tight grip. Use with fasteners that have heads large enough to make contact with the teeth, such as pan, button, and binding head screws.
410 stainless steel washers have excellent wear resistance.
