Various models of the iPod Classic include pentalobe screws on its Toshiba hard drive.
The first Apple product to include pentalobe screws internally was the Mid 2009 MacBook Pro 15-inch model. Three pentalobe screws were used to attach the battery to the internal frame. A 1.5 mm flat-blade (slotted) screwdriver could easily remove these screws, which were originally mistaken for 5-point Torx screws. This was the only internal usage of pentalobe screws; all following MacBook Pros use the “Tri-Wing” security bit to attach the battery to the internal frame, or else have glued-in batteries.
Pentalobe screws reappeared in the mid-2012 version of the MacBook Pro. Eight 3 mm and two 2.3 mm pentalobe screws were used externally to attach the bottom plate of the case to the internal frame. The late-2012 version of the 13-inch MacBook Pro was the first 13-inch model to have pentalobe screws; several were used externally in a similar fashion to the 15-inch mid-2012 MacBook Pro. None of the three 17-inch models of the MacBook Pro have used any pentalobe screws.
The MacBook Air has seen more extensive use of pentalobe screws than the MacBook Pro. All five versions of the 11-inch MacBook Air (late-2010, mid-2011, mid-2012, mid-2013 and early-2014) include eight 2.5 mm-long and two 8 mm-long external pentalobe screws. The last five versions of the 13-inch MacBook Air (late-2010, mid-2011, mid-2012, mid-2013 and early-2014) use eight 2.6 mm-long and two 9 mm-long pentalobe screws. Pentalobe screws have been used only externally on MacBook Air models.
Third-party manufacturers have marketed a variety of 5-point screwdrivers that fit pentalobe screws on MacBook models since pentalobe screws first appeared externally in the late-2010 MacBook Air.
Huawei used pentalobe screws for the Huawei P9, a decision criticised by Kyle Wiens writing for Wired, because using pentalobe screws instead of standard screws like Torx, makes electronics more difficult to repair. Its successor, the Huawei P10, also used pentalobe screws to secure the back cover to the phone.
The original iPhone had no screws holding the body together. The iPhone 3G and the iPhone 3GS had two #00 Phillips screws next to the 30-pin Dock Connector.
Pentalobe screws were first used in the iPhone 4. At first, #00 Phillips screws were used; however, many iPhone 4 models now have pentalobe screws. The screws used are slightly smaller than a Torx TS1, about 0.8 mm. If brought in to an Apple Store for repair, iPhone 4 models with #00 Phillips screws, if any, are replaced with 0.8 mm pentalobe screws. Third-party manufacturers rushed to produce screwdrivers that would remove 0.8 mm pentalobe screws after the iPhone 4’s release in June 2010. These inexpensive, easily purchased drivers will remove pentalobe screws quite easily. Many are sold as “kits” containing a 5-point driver and Phillips #00 screws, in order to replace pentalobe screws with easily removable Phillips screws. Most other security screwdrivers will strip the miniature heads, effectively locking the user out of their device.
All iPhone 4S models contain identical pentalobe screws to those found on the iPhone 4. The iPhone 5 has very similar 0.8 mm pentalobe screws, but the screws have longer 3.6 mm shafts.
