drill head off, remove face plate - shoudl be enough of the rest of the bolt showing to get a set of molegrips on it or clamp in a vice.

Try a slightly bigger Allen Key. So if it's a 5mm bolt try a 5.5mm if you can get hold of one. If it's not totally rounded off then it might be enough.

Torx bit hammered into allen bolt head should shift it. New bolt from local bolt stockist.

eBay flogs plenty of bolts if you are sure of the size, ie thread diameter, probably 5mm or 6mm (equates to M5 or M6) and the length of the thread (not including the head). So you'd probably want a, for example, M6 x 15 bolt.

Failing that the local bolt company should have them.
