Wrong! (Zeus Bolt Thrower, you too!)
Fan screws (NOT bolts!) are always (!) UNC 8 32:
N 8 - 32 UNC 0,164" 4,166mm screw 3,42mm hole 32 turns/inch0,794 turns/mm (coarse thread)
These are slightly bigger than the UNC 6 32 used to mount the PSU.
An M3 screw has a diameter of 3mm and a rise of 5 (fine thread).
This is why I decided to send u a PM to get more clarification perhaps, without "spoiling" the thread too much...
I just need fan screws of this type which are just longer
I have measured the "standard" fan screws
width head = 5 mm
length (incl. head) = 10 mm
I have checked mainly IT-service.be (Danke!) but I seem to to be able to get /find what I need...
I could also go to a shop (like Praxis, Gamma, Praktiker, etc...) and see what I find there...
Do you have perhaps a tip?
