I know you're looking for someone with a stash, and I have no idea re: availability / shipping costs to your neck of the woods, but this was literally the first item that popped up when searching for "insulated turrets" using a popular web browser / search engine combination from a company that I'm sure keeps ALL of my data.

Much cheaper than Mouser, and there are likely even cheaper sources out there.

Don't know why I missed those, looks better, muchos gracias!
Mouser ships to me in Belgium for free above € 50 order value, it's my preferred distrib.
I wonder what the insulation voltage is, it is not mentioned on the data sheet. But looking at the dimensions it should be at least 8kV.

Fifty of them for $15: https://fairradio.com/product/terminal-50-4-40/. Looks like shipping might be a problem though--$25 minimum outside US.

Edit: Electronic Goldmine has a better selection: https://theelectronicgoldmine.com/search?options[prefix]=last&sort_by=price-descending&q=turret

Another edit: Even more at Surplus Sales in Nebraska: https://www.surplussales.com/Hardware/Standoffs/dap.html

Do a search on electronic surplus stores.

@niel Davis those are nice finds. I've been buying from surplussales before (2100V film capacitors) and they're OK and reasonable shipping.
Their (TSL) PS31 looks just like the $ 5 'official' item at 1/10 the price.
And I now also know the difference between turret and post!

@as-audio I saw that but they look damaged by overheating. I'm not that desperate ;-)

With all the info given, I'm gyrating to another solution. Note that I need these for some very high voltage points, up to 8kV.
These turrets look to have rather sharp edges which would be prone to corona, while their insulating voltage isn't clear.
I ordered a bunch of those nicely rounded posts from AliBaba with the M2 thread: https://nl.aliexpress.com/item/4001007632599.html
... which I can screw into the Teflon baseplate instead on a PCB. No sharp edges. I only need to be sure I don't damage the Teflon when soldering, whcich should not be an issue according to @kb2wyl.

I think I'm all set, thanks guys!

If you insist in the form of a column it is not. You can however add a threaded standoff.

If you want a chassis solder point this model is very suitable - and it can be stacked to a
multiple solder lug column. These are standard parts from the past, I use them frequently.

Go to German Ebay if the seller is in Germany. He even has turret in the headline.
