I suggest pounding the hex wrench into the good bolt. What is that
-- 7 mm? Also grip the outside of the bolt head with a good ViseGrip
pliers. Tighten the wrench as much as you can. Apply torque with
both tools at the same time.

For the bad one, perhaps you can pound a slightly bigger wrench
inside. instead of 7 mm, you might get a 9/32. If it is 8 mm, try
to find a 21/64. Perhaps somebody will know of an easy-out.

On the other hand, perhaps pounding the allen wrench and the
ViceGrip extra-tight will be enough even on the bad screw.
