ISO 8764 has superseded JIS B 1012 in Japan as well as being used in many other countries. The standard specifies that drivers and bits are to be marked with a "PH" or "PZ" followed by the size number (000, 00, 0, 1, 2, 3), though not all manufacturers do this.

[43] Apple's first use of the pentalobe drive was in mid-2009 to secure the battery in the MacBook Pro. Smaller versions are now used on the iPhone 4 and subsequent models, the MacBook Air (since the late 2010 model), the MacBook Pro with Retina Display and the 2015 MacBook. Pentalobe screw sizes include TS1 (also known as P2 or 0.8mm, used on the iPhone 4 and subsequent models), TS4 (also known as P5 or 1.2mm, used on the MacBook Air [since late 2010], the MacBook Pro with Retina Display and the 2015 MacBook) and TS5 (also known as P6 or 1.5mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for a Torq-set screw drive.Ideally, we would publish every review we receive, whether positive or negative.
