Reference
The pin’s head is a type of hexagon head. One of the six faces has a groove.
This face is called “marked face”.
Exactly, the head is NOT
in regular hexagon.
Each face has different distance from the axis of the pin’s shaft.
For example, on step 7, a face in front of you is not “marked face”. Suppose you turn the pin
in two faces (= 120 degrees) counter clockwise, then you can see the “marked face”.
In this case, the original front face was “-0.2mm” (yellow).
