Home Assistant Yellow replacement thumb screws

I have managed to not do the one thing the instructions tell you to do… keep the thumb screws nearby. One has escaped so i am after replacements. There are no official replacements so i need to find matching screws elsewhere. Any idea what screws i need to look for?

I am now in the same predicament. I picked up my HA Yellow and one fell off between my desk and wall (and is not readily movable). I had obviously not screwed it on well.

Any answers out there?

Notice

Risk of damage to equipment

Only use the screws that came in the bag labelled CM5.
If you’re box did not contain a bag with screws for the CM5, don’t use any screws to fix the module in place
The other screws can damage the CM5 module.

The thumb screw that I was referring is one of those that secures the top of the case to the bottom. The heat sink of the CM4 is not held on with thumb screws.
