7mm Masonry screw pilot hole size

[WarrickLittle]

Hi, I’m very confused about what size pilot hole to use for a 7x70mm masonry screw going into a brick, rendered wall please. I've been getting answers elsewhere saying 6, 5.5 and 5mm?

Screw: Ulti-Mate Concrete/Masonry Screws - 7.0 x 70mm from Amazon

Thanks

It says 6mm hole on the box.

Vacuum the hole out before driving the screw as it sometimes binds

7mm in dense brick, less in block
