Please recommend screw/bolt

[Mr Sparkle]

I'm fixing a flat metal bar to the floor and wall on my bathroom. I need two different screws of the following sizes


- 8mm diameter / 70-80mm length (going into brick wall)

- 6 or 7mm diameter / 40-60mm length (going into concrete floor slab)

The screws/ bolts need to be strong (as up to 110 kg load will be imposed) and either stainless steel or highly corrosion resistant as the screw will come into contact with some water.

IIdeally, I am looking for recommendations I can pick up from a shop immediately like screwfix, toolstation, b&q etc

Got some pics of what you're fixing?

If you are fixing to a floor, then the load makes little difference, so the fixings don't need to be hefty.
