I may have found a source at current pricing via the Hardforums. Will update once in my hands.



Hehe. His rack is probably a lot nicer than mine. But does he have dual MO-RA 600's? :p

Disassembled the APC rack (I think that was the brand) chillers and pulled the rads from there. It's like 40% jank.
 
Lesson learned.

Most rack cage nuts are not 1/4" 28TPI. The cage nut machine screw may fit in a 1/4" 28TPI test thread at Home Depot, but once you order (and wait for) your specialty screws of exactly the length you want, they will not fit in the cage nuts.

Apparently the cage nuts are M6x1.0. Worth noting here. An M6x1.0 screw looks almost exactly the same as a 1/4" 28TPI screw, but has an approximately 0.4mm smaller diameter, so the 1/4" screw just won't go in.

Apparently they are close enough that the M6 screw will thread in a 1/4" 28TPI hole (albeit not as tightly as designed, this should have been my hint) but vice versa just won't work.

Can you tell which is which? 😅

After dealing with umpteen bazillion number of cage nuts... and inserts... I can see the thread spacing looks different as well.. but honestly the shorter one because cage nut screws are normally JUST long enough to thread in through a network switch mounting 'ear'.

It's actually the long one on the left that is M6x1. 😅

The one on the right is the 1/4" 28TPI I special ordered because I needed a shorter screw so it wouldn't protrude too much on the other side and interfere with stuff. :p

No idea why these are so long. I have no idea what they came with. Might have been included with the rack itself, or were a universal set someone ordered at some point. There were a **** ton of them with the rack when I picked it up on craigslist 5 years ago.

Maybe if they were universal ones they made them extra long just to make sure they would fit whatever you needed to mount.

Metric vs Standard drives me batty.

I don't really care which one - just pick one and stick with it. Ford used to drive me nuts with this.

Honestly, usually this hasn't been a problem for me. But what really threw me off on this one was that I actually brought the screw with me to Home Depot and threaded it into the hole on that fixture they have there in the fastener aisle, it fit, but of course they didn't have 1/4" 28TPI screws, (only 20TPI) so I ordered them online, and they were still the wrong ones 😅
