The only place I've seen square drive is on campers and motorhomes.
In 1970 I volunteered(I know I know) to fix the windshield wipers on this girl's mother's '58 Chevy. The cowl grille had strange screws so off to the hardware store. I found out they were clutch head screws and there were two size drivers at the store so I bought both to be sure. With all the shit I've delved into in the 50 years since I've never used them again.

I'm talking about the screw on the left but some sites are calling that one way screw you see in bathroom stalls a clutch head.

There's expensive advertising and there's free advertising...

I couldn't find a picture of the third.

That's because there's no seat-belt back there, it's for safety.
