When repairing the LCD on my sisters ipod touch 6th generation I lost 3 1.6mm screws and some other screws for the lcd shield plate. Where can I purchase these tiny screws and other types of screws for other apple devices? I tried on eBay it says something like m1.6 and m1, m2, and m3 and so on. I have never heard of that type of screws before. What does this mean?
Thanks
