I'm trying to remove a hatch to replace the acrylic cover.

Stainless steel screws through aluminum frame - 18 years old.

I haven't stripped any heads - yet. But these boogers ain't
coming out...

The only thing I know how to do at this point is to drill the
heads off and try to pull them like wisdom teeth (vice grips!)

So I am VERY open to suggestions for a non-destructive technique.
