Quoted from BeaglePuss:
You are the man!
I have some other things to order through Pinball life regardless, so this works out nicely.
The original screw has a serrated face, I assume so it will not vibrate loose. You might want to throw a lock washer on there.

Pinball Life also has these screws if you don't care which style screw head you use.
It may not matter much since Balrog doesn't have the same vibration a flipper would.
