Actually, "tamper-proof" isn't even "tamper-proof"--just
"tamper-
resistant". The closest things to "tamper proof" that I've ever seen
have been in the nature of breakaway head nuts and bolts--and
recessed hardened rivets. The only way I know of to get those out is
to drill the buggers out.
There is a type of tamper-resistant bolt head called "Bryce" or some
such thing. Every vendor has a different driver keyway pattern, so
there's no "universal" bit to handle them--and Bryce won't talk to
anyone looking for a particular bit, unless you happen to be a
licensed customer.
