What about Posidrive screwdrivers ? These are similar to Philips type of

for better grip . The relevant screw heads are accordingly.

Frank-

I've heard of Posidrive. I think they are used in an old Hewlett Packard
counter I have. However, the tool dealers I asked had never heard of
them. I ended up using a common Phillips driver for my counter.

Certainly Posidrive would be a better choice where they are more commonly
used.

In that vein, Canadians would have Robertson screwdrivers in their basic
toolbox for home use. Described, with history, at
http://en.wikipedia.org/wiki/Robertson_screwdriver .

I despise Robertson screws, along with the "Clutch head" screws.
Every time I run into either of them, someone has put them in with a
worn bit that strips the head and makes them almost impossible to
remove. I've used surface grinders, drills, and a cutting torch to
remove them to make repairs. I generally replace them with hex head
screws and make sure that I always inspect the bit before I start a job.
