What do these symbols mean in a rawl plug?

Hi,

I have found some random plugs in my toolbox and am trying to see what the symbols mean so I can put them to use. Please see pic.

what does the SX6 mean?

And what does o4-5 mean? The o has a line through it but can’t find the appropriate symbol on my keyboard.

Thanks for your help.

what does the SX6 mean?

It's made by Fischer, from their SX range, and it needs a 6mm hole in the wall.

what does o4-5 mean?

The screws you need for this plug should be anywhere from 4mm to 5mm in diameter.

o has a line through it

It's the symbol for diameter ⌀
