edit to say: one trick was to use the blank expansion slot plates to gently break the vice like grip the screw had in the hex stand-off. the metal used on the cheap "digit remover" cases was sometimes soft enough to loosen the thumb screws via the driver slot without the thumb screw breaking.
those slots were near useless.

still nearly useless though.
We referred to those blank expansion slot metal pieces as "keys." They were useful lockpicks.
