Steve,
The bolts provided by Europa are AN5-12A. Needless to say, you can get
them from Aircraft Spruce, Wicks or you local airplane hardware vendor.
I believe the ones with a drilled head are AN5-12AH and they are about
2X the cost of the undrilled.

Boy can I relate to that!! I did the same thing. Believe it or not,
no special drills are needed. Neville explained to me that you just
have to drill VERY SLOWLY (Slow drill speed and slow feed speed) with a
bit of oil. It works. Takes time to drill through the first hardened
layer, then it gets easy when you hit the softer inner metal. Don't
speed up that feed!!! If you do, you'll stick the drill bit when it
transitions from the soft metal back to the hardened stuff on the
opposite side. Just go slow and easy. It'll work.
I hope this helps.
Good building and great flying,
