Can you cut a slot in it with a Dremel tool
cutoff tool? That does a good job on hardened
material and you should be able to wiggle it and
hopefully work the broken out piece.

The hex sheared at the top of the fastener, of course, so there is nothing to grab; it also appears to be cocked in the fastener and so wonât just fall out.
Iâve tried drilling the broken hex but itâs tool steel....
