Beginner help.

Currently got my BSD and trying to get it back up and running again.

Does anyone know what size the nut head screws are that attach the parts to the playfield? I've got a full set of metric sockets but none seem to fit.

Ive also got a stripped screw head, I was thinking of grinding out a groove for a flat head but has anyone got a better method?

I have attached a photo of the screw (at the start of of ramp on the left) and the nut.

The machine screws in the playfield are 1/4” hex head x 1/2”or 3/8” length. Std playfield screws used on pretty much every game.

If you want some new ones see here

all pinballs made in the USA use imperial sizes, so a set of nut drivers in imperial is a must

If you have a screwdriver with interchangeable ends - this is a 1/4 inch nut spinner as well if you are stuck. But I would advise getting yourself a decent set of imperial nut drivers. Cheap ones dont last. Still use the ones I bought 18 years ago.
