not germane to the Op's query, but on my mind after reading the title of the thread:
when did "phillips head" screws become common?
when the family sh#t-box had a loose screw, Dad would always say "you need a special screwdriver for those" and then just tighten it the best he could using the nail file in his keychain fingernail clipper.
the repair usually lasted a couple of weeks until the screw vibrated out and was lost forever.
