Hmmm - so what sort of plugs do I use with a 4" screw?

Big ones :-)

Another solution is to use injection fixings.

You drill holes 2mm larger than the threaded stud, clean them and
inject the special resin. The studs are screwed in and the resin left
to cure for a few hours. For an item like a cupboard with fixed
centres a template should be made.


Hmm - yes I'm familair with that mechanism but it seems a bit overkill
for kitchen cabinets!!!

Depends. Are the walls brick or Thermalite blocks?

I tried using some frame fixings to make attachments into some for a
cupboard and was not comfortable with the strength of the result.

This was with fixings similar to one of the ones that Grunff listed

These don't have a lot of expanding plastic at the tip.

The Fischer ones do and would be fine, I suspect

Remember that frame fixings are normally for going sideways into
masonry and the item being fixed is normally fitted into an opening
and can't be pulled directly outwards. Really all that this type of
fixing has to do is to be able to stand some sideways force on
occasions.

Admitedly a fixing for a cupboard has to mainly stand sideways forces
also, but there is the possibility of pulling out and I feel more
comfortable with something more substantial.




These are the brackets that fit to the wall...

Perhaps I could get away with 3" screws and use these...
