Pentalobe
As Pentalobe Screw (of ancient Greek πέντε Pente "five" and λοβός Lobos "rag", according to "five lobed") Pentalobe or Pentalobular be fünflappige, petal-shaped screw head profiles for security screws referred to in products of the company Apple - the first time in mid-2009 to secure the battery in Notebook MacBook Pro - as well as Huawei - first used in 2016 with the smartphone P9.
The following sizes are common:
- 0.8 mm (used on iPhone 6 , iPhone 6 Plus , iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, iPhone XR)
- 1.2 mm (used on iPhone 4 , iPhone 4s , iPhone 5 , iPhone 5c , iPhone 5s )
- TS4 (1.2 mm, used from 2010 in MacBook Air and from 2012 in MacBook Pro with Retina display )
- TS5 (1.5 mm, used in 2009 in the 15 "model of the MacBook Pro )
Alternatively, the five-tooth Torx Plus Security profile with the designation IPR1 is used to loosen pentalobe screws .
Naming
It is unclear whether this system is correctly referred to in German as pentalobular or - as in some articles - as pentalobe . According to iFixit , Apple refers to this type as Pentalobe security screws .
criticism
Since the pentalobe profile has no obvious technical advantages over conventional screw head profiles, the previously used screws with Phillips or Torx heads were even subsequently exchanged by the manufacturer for repairs for those with pentalobe profile and compatible hand tools were initially hardly available, it is believed that the real reason Apple used them was to make it difficult for the owners of the devices to open them.
