Q: what weight do these hold

Not sure but should be at least 20 kg if installed properly

Q: Which size drill bit for these?

my fixings came in a rawlplug bag which stated drill size 8mm wall/board thickness 8 to 15mm for a plug size m4x40mm hope this helps

Q: Would they be strong enough to hold a large mirror?

The plugs are very sturdy. Depends how strong your plaster board and how heavy the mirror is!

Q: Will two fixings hold a 16kg mirror on plasterboard wall? Can’t see how much weight they can bare

You could try the rawlplug website for your answer.I think i seen weights given for these fixings on there.
