Let me know of any other heavy radiators you fit using 3/4" 8 screws.

The screws are perfectly adequate to take the load, they won't break
or shear. How ever the same may not be said for the substrate into
which they are driven, that may well fail. Into Plaster/plasterboard
no chance, into correctly fitting plugs in stone or hard brick would
be fine.
