The socket *can* be soldered, you just have to place the nut and then solder it, but replacing it would become a nightmare in case it breaks ...
I read about washers and nord lock washers seem to be a decent choice (practically impossible to loosen as the pitch of washer is steeper than the thread of the screw, so it needs sufficient force to deform the washer first which will never happen during normal use).

Edit: I can actually buy self locking nuts for cheaper ... Just need to make sure they make good connection while tightening them.

Banana sockets are not known to have problems with loose nuts... User just plugs banana plug in or out, no rotation forces envolved.
Binding posts, that do not have any rotation locking mechanism (like notch or oval shaft), may go loose.
ajb:
Those threaded banana sockets are not meant to be soldered, so it's going to be quite a challenge to do so, especially without melting the plastic bit on the front.  Just tightening the nut down is probably going to be perfectly fine.  If you're really worried about the quality of the electrical connection between the nut and the PCB, there are little washers that have solder tabs that could be used (designed to provide electrical connections for screw heads on the top of single-sided PCBs), but I can't quite muster the right search terms to find an example right now.  But I expect even a standard washer would be fine.

I'm just paranoid because I saw in one of dave's videos that one of the uCurrent units failed just because of a loose binding post, I'll use a washer

Hi,

You might want to look at Keystone 575. They come in various lengths.

I used these on my ESR meter adapter project:





These solder to the PCB.

The Schutzinger 4mm panel sockets you linked to has a data sheet link which shows a 2mm depression in the end beyond the threads.  You could solder a wire into the hole and loop it to the board to ensure electrical contact.  The threaded part could still be attached to the board and/or used to mount the board along with the soldered wire connection.  :-+
