Does anyone here know exactly what the screw size/type are used for the 13 screws which secure the Xbox MB (motherboard) and PB (power-board)?
Obviously they're Torx10 with what are called, depending on preference: domed, button or pan heads. However I've had a great difficulty actually identifying the screw length, diameter and, most importantly, the thread type/pitch.
Some sources say they're M3 (metric 3mm) but I'm pretty sure they're not; the thread is not the same as any other confirmed M3 PC screw types I have. The thread is more like a UNC type than metric.
The screw length is also open to question: using a steel rule it is difficult to tell if it is 8mm, 3/10", 7/24". Neither of the latter make any sense as they're not recognised Imperial/US screw lengths. I'm not even sure 8mm is an accurate enough measurement to the degree required for precise identification.
Appreciate any knowledgeable help on this.
