An older Challanger Main Panel


I have a 200 Amp Challanger main panel, installed in my house in 1996. I've added a few breakers and ran some wires into the panel over the years and seem to have misplaced the screws that hold the panel cover over the breakers and wires. Everything is exposed, which is not a safe condition.
Any suggestions on how to tell what size screw I need for the panel? I'm assuming SAE and not metric, but have tried 3 or 4 different sizes with no luck. Not sure what to use to determine the correct size or if there is anyway to find a reference for this somewhere.
Thanks.

Try ground screws.

Just a ground screw from an outlet or switch? Those don't fit.

I use sheet metal screws with the tips filed down.
Sometimes you need washers.

My local hardware store has them, Lowes HD, any electrical supply.
My hardware store has them in the fastner area with those pull out bins.
Says elecrical on the end of the bin.
The box stores had them in the same area where the panels were sold last time looked.
There a fine thread machine screw.
