What size screw do I need to mount the Atlas controllers/selectors/switch control

[tc1961N]

#4s are too big, do I need #2?

Thanks

Use the #2's that come with the controller/selector/switch machine. They're in the blister pack, several 2 x 3/8" wood screws. I think that's the size, but I don't have the time right now to go out to the train shed to measure them. The machine screws are for the device itself.

Thanks, I appreciate the answer! I was going to go through the 1/2" foamboard which would require longer screws but I may decide to mount the switch controls another way.
Thanks again!

I don't think you can rely on the screws to hold long-term in foam.
Is there wood anywhere near that can accept them?
