This site says my LG uses two “5.5 Phillips #00” screws, one is missing. I have gone to many websites but none use this nomenclature. Where can I buy them?

You will need to know the length too. Take the screw you have, go to a computer/phone repair store, they will be able to sell you one.

Most of the time all the screws are the same size for the Android style phones. Have you tried searching online for a set of replacement screws?
