Put a screwdriver bit in a high speed drill then rotate the whole gubbins until the plastic melts and re-adheres to the metal? Sounds like you have nothing to lose. Haven't seen one in section so I wonder how it was sealed and held in place originally.

You could drill through and tap the bolt 4mm and use a 4mm screw and fibre washer as a bleed. Wash out the swarf! Then you could counter hold the bolt to stop it rotating while you undo the new bleed screw.

Oh...............and the superglue does work.

I fitted a new radiator last year, and it has a different (and better) bleed screw arrangement.

Supplied by Raysons Radiators Yeovil. Might be made by Valeo, but not sure. £65 +VAT, so not expensive. It's not an original style replacement though.
