Why not try torx screws?
They are far easier than pozidrive.

And why didn't Robertsons screws ever take off here? The square recess
in the head really worked well. They were sold in one of the bigger
electrical retailers, but companies like Screwfix seem to regard them as
a "security" screw.

I ended up getting a load and the matching screwdriver while doing a
theatre installation job in Ireland and I thought they were great screws
to use.
