Are there any test probe/connector options for plated through holes in PCB's?

Hey guys i've been playing around with PCB's and for a while i used to make my own probes for plated through holes (see attached pic).
Making them is quite tedious and requires that i have that one special floppy drive connector to pull the contacts from.
So i started wondering if there are any off the shelf connectors that i could perhaps use?
From what i've found there are insertable (or solderless) connectors, but they're mostly single use and deform both the PCB and the pin itself upon insertion, while some are non-removable at all.
What i'm looking for is a probe that can obtain a good mechanical connection to the plated through hole without damaging the PCB.
Pogo pins are also not an option because i don't have anything to hold them down onto the plated hole to keep them secured.
I've seen some japanese manufacturers who can custom make connectors that are re-insertable for up to 40 times IIRC, basically what i'm looking for but they're custom order items.

Would appreciate any pointers to the right direction, assuming that what i'm looking for even exists.

The hard bit is finding what they are called.

But seems extremely likely they do exist.

Yes exactly this, because when i searched for them it sometimes seemed like i've seen everything but then i find another keyword and it's like it opens a whole new chapter of search results.
I also expect there to be something because it seems like such an easy and convenient way to connect to existing through holes that surely there has to be someone who has already made probes for it.

I imagine they will probably be constructed with a cylinder inside two half-cylinders with a spring on the top.

The spring forces the pin down a channel between the two half-cylinders expanding the overall diameter and locking the thing inside the TH.
But you can release them and the pin retracts reducing the diameter so you can remove them from the TH.

That's what i'm thinking anyway.

That's along the lines of what i was thinking also. Some ZIF solution, like one of those clip-on probes that hook on pins, but for holes.
