Stainless hex masonry screws - where can I find some?

In the UK, that is. Easily available in the US and Oz but I can't find the right search terminology to source any in the UK..

To fix sub floor cls, on membrane, to conc. base. I sealed with Sikka rapid dpm and will completely cover with membrane too.

Thank you.

Do you want to screw into concrete?

 

Thank you, yes. Original query revised.

 

Coach screws?

TIMCO might make them as well.

 

For your job, where there is not much force and it is just to hold steady, a stainless coach screw in a plasplug would do.

 

It's more to stop it springing up adjacent to where any significant weight might be applied, that's why I wanted the threaded option.

 

Ah, also slightly cheaper at https://www.adafastfix.co.uk/Products/Stainless-Masonry-Screws
