Looks like a standard late Rover wheel nut with the chrome/tin cover missing - makes them easier to undo IMHO but they don't look as pretty (cosmetics surely the only reason for those crazy capped wheel nuts) - looking more closely they may be mid 80s wheelnuts for steel wheels and using those large full width plastic wheel covers (held on by the washer
Sorry I can't answer you direct question - as to whether these would work with the Mini Special Exacton wheels - you need a nut that has a seat to match the wheel (taper or round or a tube nut if the wheel is so designed - like a mamba)) and I believe Exactons had those NLA plastic covers (but now available on Ebay 3D printed) - what nut they are designed to go on sorry can't help but you say you ordered an Exacton wheel nut - can't you get a set of those if they ARE the correct ones? and do the covers fit those if they are Exacton wheel nuts?
