Sky Jump
Gottlieb, 1974Hey guys, I was tightening up some switch stack screws on Sky Jump and found one that was stripped. Does anyone know what size these are? They look like they have a finer thread than a 6-32, maybe a 6-40, or 5-40?
I’m putting in an order for PBR soon and would like to know what I’m looking for before contacting them. Thanks.

Thanks guys. Here’s where the stripped screw is from, the switch bank for the 1-7 rollovers. Sorry about how dirty it is, I’m not good at cleaning the inside of these things. Please don’t repost this in the “horror pics” thread.
I would like to invest in getting an assortment of hardware to have on hand for cases such as this. Any suggestions on what I should stock up on?

If in doubt, buy ones that are longer than needed. You can cut them down but you can't make them longer. Not ideal but works in a pinch. Another trick when cutting them is to screw a nut on the fastener and run it all the way down. Then after cutting, remove the nut to clean up any burr on the cut end.
A thread gauge is handy for checking them: https://www.mscdirect.com/product/details/84395755
Another option is to acquire a couple used units as parts donors (ie., steppers, score motors). I have good luck finding them on eBay.
I scavenge switch stack screws/nuts (like you’re looking for), plus switchblades, springs, Bakelite switch spacers, and various other hard to find parts from them.
