1 Where can I find the bottom case screws with the shoulders on them
Hello, I have a mid 2012 MBP 13” A1278 computer, and I am missing two the case screws that have shoulders on them, as this computer requires a total of 4 screws with shoulders on them.
I looked on the ifixit store and apparently there is no mention of screws with shoulders on them.

However when I am looking at one of the teardowns for the 13” MBP A1278 mid 2012 there is clear picture describing three different types of screws.
Is this a good question?
