Initially, automobile manufacturers used 6-pointed Torx screws to lock emissions units in automobiles– now they are found everywhere, from mobile phones to residential construction. Even Apple jumped on the tamper-proof train with the original 128K Macintosh.
The reverse-engineers of the world found a way to un-screw themselves by creating Torx bits, Torx Security bits, and, in most recent years, Torx Plus bits. Now, any member of the general public with access to a hardware store also has access to their Torx-guarded things.
