Thanks, Specter. I did in fact order a set. In the meantime, I found a pair of calipers and measured the screws that came with my H100i. They measure at 0.1315, at the very low end of the tolerance spread for the 6-32 standard. The other 6-32 screws I have ordered, from two different suppliers, measured right around 0.1350, i.e., right near the middle of the tolerance ranges, which are as follows:
0.1312 - 0.1372 (2A tolerance class)
0.1320 - 0.1380 (3A tolerance class)
This is pretty abstruse stuff, but given that the mounting holes in the radiator are so fragile--because of the softness of the aluminum--it is probably good to know that any replacement 6-32 screws you might get are likely to widen the holes enough that the stock screws will no longer hold. I have found threads online complaining of this problem even when trying to use the stock screws on a reinstall of the H series radiators. So, screw carefully friends!
