Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?

Re: Threads for screws on 8656 Siggen
(32 threads / inch) * (1 in / 25.4mm) = 1.2598 threads / mm
1/1.2598 = 0.79375 mm / thread (pitch)
That's not even CLOSE to 0.6mm pitch
(42 / 25.4) = 1.65354 threads / mm
1/1.65354 = 0.6048 pitch
