Precision Pentalobe Screwdriver Set, 0.8 mm, 1.2 mm, 1.5 mm (P2/TS1, P5/TS4, P6/TS5) for Apple iPhone, MacBook Pro, Air Retina

Product Information

The iPhone 4 has one of the smallest screw heads we’ve seen, probably for cosmetic reasons. This 5-point Pentalobe screw is actually slightly smaller than a Torx T1. Yowsers that’s tiny. The shape looks a little rough because this tiny screw is giving Apple’s manufacturing process a run for its money. Current MacBook Air Fortunately, our always-creative hardware acquisition team has been on this problem for a while. It’s our responsibility to provide you with all the tools you need to work on electronics, and we have a solution for you! iPhone 4

Apple is switching to a new type of tamper-resistant screw. This is not a standard Torx, and there are no readily available screwdrivers that can remove it. This isn’t the first time they’ve used this type of screw—it first appeared in the mid-2009 MacBook Pro to prevent you from replacing the battery—and Apple is using a similar screw on the outer case of the current MacBook Air. This screw is the primary reason the 11″ MacBook Air earned a lousy repairability score of 4 out of 10 in our teardown last October. These pentalobe, 5 point heads are not to be confused with Torx heads which have 6 points. A "IPR" designation identical to "PL" is sometimes seen due to the confusion. It is possible that ambiguous "TS" nomenclature is the same as the "PL" designation when referring to Pentalobe screws. Pentalobe screws reappeared in the mid-2012 version of the MacBook Pro. Eight 3mm and two 2.3mm pentalobe screws were used externally to attach the bottom plate of the case to the internal frame. [5] 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. [6] 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 2.5mm-long and two 8mm-long external pentalobe screws. [7] The last five versions of the 13-inch MacBook Air (late-2010, mid-2011, mid-2012, mid-2013 and early-2014) use eight 2.6mm-long and two 9mm-long pentalobe screws. [8] Pentalobe screws have been used only externally on MacBook Air models.The pentalobe will always be associated with Apple. But recently, other manufacturers have piled on the five-point-screw bandwagon, too. A couple years ago, we spotted our first set of pentalobe screws outside of Apple’s ecosystem—first in Huawei’s P9 and then again in Meizu’s MX6. With no real functional reason for choosing this screw, I can only assume it’s to look more like Apple’s most popular devices. A rose-gold iPhone sits atop the Huawei P9—both featuring Pentalobe screws. Meizu’s MX6 (the silver one) sits in between two iPhones. From this vantage point, the three phones are almost indistinguishable—right down to the pentalobe screws. MacBook Air 11" Late 2010 Teardown". Repair Guide. ifixit.com. October 10, 2011 .

TS-sizes are sometimes used, but leave room for mixing up with regular Torx sizes. The following P and TS sizes are used by iFixit.com, and PL sizes by Wiha, a German tool company:

The largest 5-point Pentalobe screw used thus far was deployed in the Mid-2009 MacBook Pro. Apple calls this a “Torx Plus Tamper 6.” For reasons known only to them, Apple has switched away from these screws and is using Tri-Wing screws on current MacBook Pro models. A compatible Tri-Wing bit is included in our toolkits, so you don’t need to worry about this if you have the latest MacBook Pro. iPhone 4 Pentalobe screwdriver sets are a must-have for anyone who frequently repairs or maintains Apple products such as iPhones, MacBooks, and iPads.
