This alternative multi point nut was preferred by racers because the plastic locking part of the original AEG147 could fall out under extreme conditions on an over hot running engine. Current AEG147 are now an all metal nut with special gripping qualities. The built in flange of this latest specification multi point nut helps to spread the load and improve clamping force. sold singly 8 required per engine
