Plasterboard fixings

rickyroma

I'm hoping to hang a 20kg mirror from a plasterboard. Nowhere near a stud so I've got to get the right fixing. I've seen the large hole grab it ones suitable for TV brackets but these seem to depend on tightening the bolt up... I need to leave an inch or so stuck out to pop the mirror loops onto. 
 What fixing is best for leaving the bolt untightened?

Why not use the bolt to fix a hook for the mirror?

Lol 😂 that would work

Gripit or geefix would be the safest probably, they go up to 80+kg!

Fischer duo plugs would probably do it tbh, you can see the ratings online and watch some needy YouTube videos showing tests!

I'm thinking in my head a 20kg mirror has to be near at least one stud, it's so heavy it has to be quite big, and timbers are normally only 400mm apart?

This type is my goto for projects like this -

As per @Jonboy_1984 above I used Molly Bolts when putting up a large mirror recently (although I'm not sure it was as heavy as 20kg).

Screwfix do M5 and M6 thicknesses and also different lengths:

They also do the setting tool that you would need to fix them into place:

If you have a scrap bit of plasterboard or piece of wood I would recommend doing some tests and familiarise yourself with how they work and how to use the tool.  It's possible to fix them without using the tool but I wouldn't recommend it because there is scope for them to become deformed and since you can't see behind the wall you have no way of knowing.

Fully agree about using the fitting tool ,tried installing some of the hollow wall fittings by just tightening them up with the screws supplied and made a right mess .

The grippit fixings are brilliant, and so easy to use! The brown ones are holding my kitchen wall cabinets up so they definitely will take your mirror! 😊

Buy a small pulley.  Fixing goes through hole in centre so can be fully tightened, Cord over pulley so no danger of fraying on sharp edges of bolt thread.  I used one from an old Meccano set
