For an old 19" rack, I need to buy some cage nuts for round holes. You can't get them here in the Netherlands, it seems, but Amazon has them. However, I don't want to get US sized thread…
Amazon says that the above product is 10-32 (US size) and M5 (metric size), but this PDF states that a M5 bolt in a 10-32 nut will strip the thread ("The screw can be forced into the nut but the thread is stripped").
So, does anybody know if they are indeed M5?
Or, does anybody know a Dutch supplier? I've asked a whole bunch, but no one has them anymore…

There's no precise M5 equivalent but I think you'll be fine with either a 10-32 or 10-24 depending on TPI, they're cheap so just buy both and be careful with the first one. No idea on a supplier in NL though sorry - oh and consider changing out the four mounting poles to square ones - they may not be too expensive and would mean you wouldn't have to worry about this problem again.
Good luck.
