Is the problem that the Nano header pins don’t fit in the socket? IC sockets aren’t really made for pin headers, but you can usually squeeze them into the ones with square connectors, but they won’t fit into round “machined” connectors.
(also note that the Nano has 30 pins, not 32 pins, so unless the PCB has extra holes you need to trim off one pair of connectors)
Otherwise, you can use female pin headers instead, which are a bit taller but are designed for this purpose. Tayda has 15-pin headers but if your favourite supplier don’t have that you can just get longer ones (40-pin units are common) and cut them to size.
As they’re specifically designed to slot into female headers, a custom socket isn’t necessary. Simply solder two rows of female headers onto the circuit board. The easiest way to get the distance and angle right is to first mount the nano board onto the headers. The headers themselves are designed to be trimmed to the correct length to match the board.
I made the same mistake with the machined connectors on 2 of my VCO’s. Gonna have to desolder them eventually. I bought some 40 pin leaf type to trim down instead.
You notice under all the pictures on Mouser it says

which means “here’s a picture of something kind of similar we had lying around”. It might be a 14 pin socket on a listing for a 32 pin socket. It might be a D shaft pot on a listing for a round shaft pot. Who knows. The product will be something akin to the picture but always check the description and data sheet.
You’ve got me curious about how that works. Could you post a pic of the Arduino and how they’re attached? I picked ups that same bag and was disappointed that they wouldn’t hold the square DuPont pins. If you share your solution maybe I’ll feel like less of a bonehead!
I just pushed em on, They don’t seat very far but definitely not going anywhere. When I get home today I can show you one but I don’t think there will be much to see
I’ve got a whole batch of 40 pin single and double headers, male and female. They’re handy things to have around if you are into through-hole soldering and sometimes have to use breakout boards (which is essentially what an Arduino nano is for the surface mounted ATmega328P-AU and its external USB support chip.)
No, I understand that. I was just saying this in my post so people didn’t look at the photo on the link I posted and think that I had bought 16 pin sockets instead of 32.
Do you guys think that I can put a row of pin headers on top of the IC socket I have soldered in and then put the Ardunio on that or will I definitely need to desolder the IC socket that I put on the board and then place some new pin headers on? I’m just asking because last time I desoldered something I didn’t ask before I did it and then found out that I could have actually left what I had desoldered in place. So I figure this time I will ask. Not to mention last time it took me 3 hours to desolder 1 part and fit a different one on
If you’re talking about putting a row of female Dupont pins into the socket so that you could get the normal male pins into that, then I’d guess you were going to have trouble with the female rows staying in unless they’re the machined version that @CTorp is demonstrating above, but then you get into the issue we were talking about with the fit. The worst that could happen is that it doesn’t work and you learn something to share with us though, so give it a shot!
So Mouser is upgrading everyone’s order to next day so I got the parts this morning that @fredrik recommended. The Arduino does fit in these sockets so that’s good news. What I was asking about is if I could stack them (like in the attached photo) to avoid desoldering the other socket. I obviously didn’t press these down in the photo, but I know for certain that they will all fit together. I don’t know if by doing this it will be a problem and right now I have no way to test any of the modules I’m building.
