Looking for 3mm OD Round Coupling Nuts/ Round Standoffs

[UncLeJunkLe]

I'm looking for a place to buy (China or USA) round coupling nuts or round standoffs within the following specifications...

OD: 3mm (but could go as wide as maybe 4mm)
Thread size: M2 preferred if even possible for a 3mm OD nut, but smaller could be OK.
Material: Preferably stainless steel but that's also not a 100% requirement.
Length: Minimum of 6mm

What I'm looking to do:

To convert floating pin 510 heat sinks...

...into threaded pin heat sinks (which are hard to find anymore)...

Not Sure if these would work...

... but the Price is Right if they Don't.

Man, I'm so terrible at searching for this kind of thing.

Those to seem to possibly be a good fit. I'll wishlist it. Thanks.

Just wanted to post an update and to say thanks. I ended up buying these except I went with the 5mm version because they were stocked in the USA. Same as the one you linked to.

Being 1mm shorter would possibly pose an issue if I were to use screws with heads that are flat on both the top and bottom, like the ones in my 2nd pic. But I'm using countersink screws and I think the 5mm ends up being a better option because of that. Regardless, now I can turn my floating pin heat sinks into adjustable ones?

Good to hear UncleJunkle.
