360 Controller Replacement Screw Size

[Trojan Horse]

Does anybody have any idea what size I can get a bunch of these screws in for... need a few for some different controllers I have lying around

about 20-40 but will be fine with extras so just want to know the actual screw size so I can buy some cheap flat/ philips heads (easier to work with I suppose)

cheers

Well does anybody know how I can measure screws to search for?

I've got two screws and a caliper so if anyone knows how I can work out torx t8 screw sizing that would be nice

Thanms
