The length of a screwdriver varies from 50 millimeters i.e., 2” to 18”.

The pentalobe screw drive is a five-pointed tamper-resistant system implemented by Apple in its products. [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.
