Where to find bt2*5 screws?

Bambu Lab A1 Series
1

In the process of replacing my hotend heat unit, I had to unscrew the extruder PCB. I have stripped and lost 2 out of the 3 screws here and am in need of bt2 5 screws. I tried doing a search online and I have found NO PLACE that sells these types of screws ANYWHERE. I see pretty obscure hobby sites that sell bt2 6, but absolutely no place that sells bt2*5.

What makes this even more confusing is that when I go to the spare parts page and look at the extruder PCB, they ship with M2-2 screws?!
Here’s verification on their hotend heat unit replacement wiki page, that the screw needed is a “bt2*5”, which is “screw C”:

Wild guess, but are these not just button head 2mm by 5mm long screws? So M2’s? Maybe this. If so, there are many like this on Ali. You can also find different head types (e.g. hex head) if you look around.

I have a pack of M2 screws and the thread pitch is not the same as BT2 screws. I really wish Bambulab made a screw set

Button-head Thread-cutting screws for plastic. Number #2 size. Not! M2 thread.

Get the 6mm length wherever you can find them (RC hobby store) and grind 1mm off the tip (so they don’t go too deep)

FYI the Motor Hardware kit has 58ish of the BT2-6 screws.

weirdly enough, the US version of this kit does NOT include these screws…??
