Thanks, if the screwdriver is larger then iPhone screws, then is it same as MacBook or MacBook Air? Still looking for competitive screw driver. Thanks.

There are as I said only 3 sizes of pentalobe screws. The ifixit 54-bit screwdriver kit has all 3 included. Or you can get the pro tech tool kit. That includes the bit set and much more.

Although there is no (known) official standard naming-scheme; the size is commonly known as P-sizes. TS-sizes are sometimes used; but leave room for mixing up with regular Torx Sizes. Many sources are using the wrong scheme (i.e. mixing P- and T- naming). The following sizes are used by iFixit.com:

Pentalobe sizes

P-Sizes TS-Sizes Dimension Usage

P1 TS0 Unknown Unknown

P2 TS1 0.8 mm iPhone 4, 4S, 5, 5C, 5S, 6, 6 Plus

P3 TS2 Unknown Unknown

P4 TS3 Unknown Unknown

P5 TS4 1.2 mm MacBook Air and MacBook Pro with Retina Display

P6 TS5 1.5 mm MacBook Pro (2009) Battery - 15” only. Also known as Apple specialty tool 922-9101

So I've purchased a 0.8 and a 1.2 pentalobe driver and the 0.8 is too small and the 1.2 is too big... Can anyone confirm one that they've bought and personally used to work?
