Fischer KT Spring Toggles 5 x 50mm Pack of 20
More Info Please
50mm seems plenty of length but the toggle needs a good inch before it will open. Unless you are fixing something thin to plain plasterboard you may need a longer fixing.
Come on Screwfix why can't you provide information like this on you website. It's on the packaging so can't be that hard.

don't forget to measure the thickness of wall, you may need to purchase a longer screw size.
