Screw, Separator, D2
Replacement screw (bolt) for the model D3A and D2 Rainbow and is designed to match the plastic separator that has a beveled edge around the center hole. This bolt under the head is chamfered to sit in this beveled pocket.
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.
