Screw, Separator, D2
Original screw (bolt) for the model D2A and D2 Rainbow. Designed to match the metal separator that has a flat center hole. This bolt under the head is flat to sit flush against the separator.
Works with the female type armatures found on the above original motors. If your motor has male threads on the end of the armature, then this is NOT the correct part. You need to order an H524 or an H555 separator nut.
