Jelly Bean man's answer does not follow the standard screw callout format and has incorrect information even in the "corrected" edit.
You do not use the overall length when giving a screw size, you only use the threaded portion as the length. You also do not give the length after the major diameter, the number after the first x is the thread pitch.
The standard format for a metric screw callout is: [br]
[br]
major diameter x thread pitch x threaded length
The screw sizes are as follows (units are mm):
* ***Exterior screws: M2.5 x 1.12 x 8***
* ***Pak port screws: M2 x 0.89 x 8***
* ***Joystick screws: M2 x 0.89 x 6***
*
The screw type is thread-forming for plastic, with a pan head philips drive.
