Been putting this off, but SWMBO is putting the pressure on. I have a
fairly heavy oak framed mirror, which is to go over the fireplace.

I am not sure that nylon cord over 'J' hooks will hold in the long
term, and was thinking of using those flush fixings that screw to the
wall & the mirror and then interlock. Problem is, to ensure that
they fit together, they will only take a No.4 screw. This is fine
for the mirror plate, 4x No.4 1/2" will be fine.

Any suggestions as to what I use to fix the 'wall' plate? It will be
fixed into concrete blocks so rawlplugs will be fine, only issue is
that No4 screws are too small!!

Any suggestions as to how I can fix the mirror or the wall side of
the flush fixing? To be clear, anything larger than a No.4 will stop
the plates from locking together.

Could you not countersink the holes a bit more so a larger screw will sit
flush?

Tried that on a spare, but the metal is too thin - I fear it would tear
off the wall.

Use a french cleat:

I have used something similar to fix numerous mirrors, cabinets, pictures
and items of heavy furniture.
