If you have double layer of plaster board the suggested fixing will not be suitable as they expand behind the board , they are likely to expand in the rear layer making a mess, the head is also very large making it unsuitable for many hanging fixture which require a specific size of screw. You could use a conventional plug if carefull as you have nearly an inch of plaster board, tighten screw slowly, or you could use these nylon fixings which allow a greater choice of screw.

They are screwed into the plasteboard using a screwdriver before fitting the screw, with two layers of plasterboard you will need a pilot hole or you risk tearing a hole.

The head requires a 10mm hole so is not very large and the fixing can clamp up to about 90mm.

And in the unlikely case he has two layers of plasterboard, they do these:

They come in M4 and M5. Either should work fine with just about anything.

Yep, and they leave a massive hole if you have to take them out, and don't hold as well because they compromise the plasterboard.

Many of the Ikea cabinets slot onto a 6-8mm screw head so they are too large in many cases, and some cup's cannot be screwed thru the inside so they have to slot over the screw head, but not all.

I think you will agree Tinks appears to be a novice and needs as much advice as possible.
