what size screws used on a SS 80’s Williams

[AlanJ]

Hi just got back to my Williams Cosmic Gunfight project. There are quite a few screws missing from several mechs eg flipper coil end stops and outhole kicker coil end stop. none of the screws i have spare seem to fit (they do on bally machines). looks like the williams ones are smaller diameter. smallest i have is 6-32. so I guess these maybe 4-40?

Can anyone confirmmplease

6-32 is usual. 4-40 is hardly ever used. Just a few special cases. I would try the 6-32 again.

Aha i retried the flipper ones with a nee 6-32 screw and it fitted.

the coil stop for the outhole kicker is deffo smaller. I’ve found a couple of BA4 screws which seem to fit that, but the 6-32 was deffo too big.

many thanks for the help @pinballmania
