Cloakroom Sink Hollow wall fixings

I have a problem fixing my small 35x28cm cloakroom sink to my hollow wall in the cloakroom, these sinks come with a concealed fixing for a brick or masonyry wall. Unfortunately builders these days like to use hollow walls so the alternatives to fixing this to the wall are very limited!
- I have to have a hexagonal head behind the basin as screwdriver access is impossible
- I cannot find a machine screw to fit a toggle bolt as that may be sufficient?
- I cannot find a suitable hollow wall plug that would give me enough strength or can fit in a hexagonal headed screw of some kind.

I cannot believe no one has not had this problem before in a modern house? I am under the impression from merchants that they dont, or just stick it up with no-nails adhesive or silicon?? well I like to to a good job, so can anyone offer some experience of advice as I have a sink that is only good for the trash can.

P.s. the only other solution offered was to rip down the wall and add an extra stud partition supports, this is not really a viable option as a lot opf replumbing would be required and also the board is not a standard size depth.

Thanks if you can help.

Unless you change the sink to a pedestal type which will take the weight from the floor or a base unit.

Or cut a narrow section of the plasterboard and put in a noggins so the basin will hide it.
spring toggles are available in 5 or 6 mm size

hex set screws are easily available in these sizes - try a engineers merchants
