Thanks for replies, quantity is very low, so bothering big manufacturers won't be worth it for neither me or them. I was simply thinking that these may have some special name I haven't heard of.
Anyway, figured out a solution with something that I have on hand and that won't break the bank also, 1.5mm ferrules, stripped off the plastic, slide in, tiny amount of solder to hold it, flatten the back side, reflow the solder, done.
