The issue of screws that are included

[Anton 0]

Hi all.

 

I do have lots of TT's Riing case fans:

- Riing 14 LED RGB Colors (oldest one)

- Riing Plus 12 and 14 LED RGB Radiator Fan TT Premium Edition

- Riing Trio 12 and 14 RGB Radiator Fan TT Premium Edition (finally got it !) 

All fan's boxes have long screw (pic attached) that are metric M3 threeded. But not UNC #6-32 that is used in all PC 's cases/radiators. How and for what use it? I have like 50-60 of such useless screws. I have a pain and I am suffering with attaching fans to radiators in my PC.

So my question is why long screw are metric and not UNC#6-32 ??

 

Thanks in advanse.
