Fender Professional pedalboard - which screws for the panel jacks in the back?

[luckymethod]

I recently purchased a medium sized Fender Professional pedalboard and I'm in the process of building out. I bought some switch connectors for the back panel and what I don't know is which screws I'm supposed to use to fix the panel jacks to the pedalboard. Can't find the info anywhere.

Thanks in advance!
