A special large washer to enlarge the head of standard Anti-Pinch pins.
Dimensions are 120mm (4-11/16) diameter by 6mm (1/4") with a center hole slightly larger than the 23mm pin.
In cases where you want to use the Anti-Pinch in through the hollow wheel hub, the head on the Anti-Pinch pin could be too small. This large washer effectively increases the head surface.
