It's really quite simple, whatever fastener is most efficent in manufacturing is the fastener that is used.

It's hardest to strip a torx. Since Robertsons aren't used as mechanical fasteners (except 3/8 drain plugs in pumpkins) Torx is used. Why not Allens? ask anyone who's ever adjusted/installed Sloan hands-free faucets how the 5/64 brass allens just suck.
