Can anyone give me a bit of advice?

Hello.
I've now got several sheets of hardiebacker board to line my shower enclosure. I spoke to their customer support team the other day and was told that I need to use galvanised screws (I'm guessing masonry screws) to mechanically fix them to the wall in addition to dot and dabbling them.
Does anyone have any experience of doing this and could someone please tell me where I can get a galvanised masonry screw.
I'm getting a bit fed up of having to take baths.
Thanks.

screwfix or toolstation would be good for your screws, basically you want screws that wont rust, although they say dont dot and dat it to a wall, personally i would to get it flat/straight easier, once its set then screw and plug them to the wall through where you dot and dabbed ....unless your wall is perfectly flat just screw it lol!!

This is where I am having a slight problem, I'm not sure how rust resistant I need these screws to be. The ones in toolststion are ' zinc & Yellow Passivated' which are not suitable for exterior use.

Having said that, if the screws are going to get as wet as if they were outside then I've not tiled my shower very well have I?
Does anyone know if this degree of rust resistance will be sufficient or can anyone recommend a particular type or brand?

I use the Turbo screws from screwfix 25mm in length....
