From this detailed disassembly video,
https://www.youtube.com/watch?v=_l5SFWA69I0
The tools needed in order of disassembly are:
1)Pentalobe tool of unknown size for bottom panel screws
2)T4
3)T5
4)T6
5)Pentalobe 2
The problem here is that the video does not explicitly say which size
pentalobe tool is used to remove the bottom panel screws.
When it comes to removing the Wi-Fi screws, the video again says the
screws are pentalobe 2. Does that mean P2 or PL2?
Another video gives more specific information when the size in
millimeters is given along with the P(L) size. That is very helpful.

Wikipedia has a good chart which explains how the same sized screw can
have *four* different names for one specific size.
https://en.wikipedia.org/wiki/Pentalobe_screw
After reading all the information about these disjointed standards for
these pentalobe screws (and explained previously by whit3rd further back
in this thread), what makes the most sense to me is to make sure you
confirm the correct screw size with the measurement in millimeters of
the screw. For example say, "Pentalobe screw size 1.2mm," not,
"Pentalobe 5."
On a side note, there seems to have been a successful lawsuit against
Apple for their faulty displays.
