The screw is for adjusting the interior.

The screw is spring loaded to adjust the bus (in or out) to fit properly with the panel cover. Has nothing to do with amp rating.

It was a vital part of the cover, as FPE breakers, due to the design of the off/on mechanism, will pull away from the buss when they're turned to the on position. The interior depth screw, when properly adjusted, theoretically held the breakers in place.
It would be wise to replace the panel ASAP

There are other panels with flush covers that have adjustable interiors to match the interior up with the cover, they are not always adjustable with cover installed like this one is. It is not an FPE only thing.

NO
you don't turn the screw to raise the voltage. Nor to adjust the amps
In the photo, the instructions for the screw is above the screw.
