Ring terminals with captive nut

[GTWreck]

I'm working on hooking my engine probes. The CHT thermocouples had an interesting ring terminal attached to it that has a nut welded or pressed onto the terminal ring. I've never seen this before. I can see a use for them in some cases, but I can't seem to find a source for them.

Does anyone know the part number and a place to order them from?

Looks like a PEM nut installed on the ring terminal

The easiest thing to do is call the manufacturer of the probes/instrument and ask for some spares. They might even send you some for free...

If not, I bet they can give you a part number.

You see those a lot on certified probes with PIA slotted 6-32 screws. Sometimes soldered also, depending on wire type. They're kinda old-timey. Supposed to have fabric tubey thing laced over each terminal. Bulky. You could no doubt crimp on new connectors and never know the difference electrically.
