I’ve assumed that you were refering to the later rotor to hub  
locating system, as depicted by Bentley 46.10e, and is mine, using  
the screw and cupped washer. Maybe not?

An impact drive needed? Why, don’t you guys keep the interface  
surfaces on hub, rotor, and wheel clean and lightly greased for the  
needed face alignments and moisture exclusion? That Philips screw  
need be no tighter than a light snug.
