Just picked up an APC 48u rack. The listing had no shots of it, and I didn’t notice till after I got it home and set up, the rack rails do not have square cage nut holes, but what appear to be threaded holes. I can not find a bolt or screw with the right size and thread pitch. It looks like it’s an M5 fine thread, but wanted to see if anyone had any info on this. Am I just supposed to get self tapping machine screws, like the previous owner did? Or is there some APC proprietary bolt that I’m working with here?
I work in automotive, nuts and bolts are my job. Miss-threading because of laziness is unacceptable lol I’ve used everything in my bolt bins sae and metric…
I agree.
Does anything work on the threads in the back or are they the same?
It is incredibly unlikely all the threads are screwed, despite my story.
If they truly are, you should be able to buy replacement rails. If you do, I’d say go square if you can and use rack studs for ease of install.
All threads are the same. You can tell the holes that they used by the threads that are messed up. Looking up replacements, can only find 42u hight and cage nut…. APC wants $1200 for the set… only paid $200 for the rack.
Go buy a tap and die set from Harbor Freight for $20. Make your own threads.
Lol this is exactly what I was trying to avoid.
They must have hired the guy we got rid of. Bummer, dude. Might have some luck at an IT recycler nearby. Contact them and tell them what you’re looking for.
At this point I might as well just use self tappers myself, not planning on moving much around… but nothing ever goes according to plan lol
I mean if the U label sticker being off an entire hole isn’t a giveaway that someone’s not competent…
Further inspection revealed that they were all off, and were pieced together by fragments… I’m pealing them all off and have a white sharpie
