This is the nut that secures the rotor onto the crankshaft, found in the crankcase section of the parts books. It shows up across catalog listings from 1969 to 1970. Even though the manufacturer field on this one reads BSA, the description and figure placement point to it being cataloged with crankcase hardware for this era of engine.
