Bag of bolts.
Good old bag-o-bolts, only these have the weirdest triangular drive socket I've ever seen. Even my 25-piece security screw driver set, able to remove just about every kind of screw that is meant to be hard to remove, doesn't have a driver for these. I guess it's a kind of an arms race, and right now these screws are winning. Made of aircraft titanium, of course.
