Allen head type or standard bolt head (also a hex since it has 6-sides).
If a standard type bolt try the stripped bolt remover from Sears/Craftsman. It is sharp and reverse threaded to bite in to the old head. If the allen/hex type I know that grinding a small slot in it might allow you to use a wide screwdriver or similar.
Hope it works out.
