I want to fit a towel rad to a plasterboard wall. The fixings that come
with the rad aren't for plasterboard unless fixed to timber noggings in
which case the instructions say to drill a 4mm hole for the screws.

Naturally there are no noggings where I need them so I am looking at
plasterboard fixings like these

But I'm not sure what the 'spec' is - the description is "Hollow wall
anchor 5 x 52mm 8-16mm"
I take it the 5x52mm means 5mm screw, 52mm length. But what is the "8 -
16mm"? Is this the size of the hole in the fixing I want to put in?

Also this fitting

"Metal plasterboard anchor 5x37S" - what is 5x37S - 5mm x 37mm? What is
the 'S'?

Thanks

I would say that your only safe option is to take a strip of
plasterboard off and PUT in noggins.

Unless you have tiled the wall, in which case ordinary screws and
rawlplugs will just be adequate.

As a long term dweller in stud work houses, you get very used to carving
out a chunk of board with a Stanley knife, inserting bits of wood to the
studs, and sticking the plasterboard back and re skimming, sanding and
painting.
