Removable links threaded at sloted end

[Zsprings]

Recently looking online for a white gold link, I noticed the 15.5mm spare links for the SkyDweller appear to have the thread under the slotted end. This along with a white sleeve which apparently goes into a larger diameter hole in the link, the pin therefore needs to be free of threads to able to slip through the white sleeve? Am I correct? To make it clear, I was'nt looking for a SD link, just a 15.5 link for bracelet 78219 which has threads opposite end to slot top.

Yes, some of the newer bracelets have gone to an actual bolt/rod, with the threads at the cap screw end. This type would need to be tightened (torqued) as you would any bolt. This also means that the links are different and not interchangeable.

The older bracelets were basically studs that, when screwed into the opposing link, did not have any clamping force so there was nothing to tighten them against, hence, the usual need for loc tite.
