Screw size for HRAP 4 Kai bottom panel

Just curious if anyone knew the size of the screws on the bottom panel of the stick. The screws on mine are starting to strip a little bit, and I don’t want that to become an issue later.

The screw heads or the threads in the plastic?

The threads, sorry

You over tighten the screws, thats what happen.
Best you can do is take the screw to a hardware store and ask for a size bigger
