Those are (likely Headway LiFePO4) cells that are manufactured with screw terminals, e.g. see here. I don't recall ever seeing such on 18650 cells.

two of my builds. soldering isn't really recommended but i have a technique that takes less than a second. i soldered these in 2014 and they're still holding up really well

i know soldering to batteries is not good and all the companies use sonic welding to accomplish connecting their terminals to the cell.
i've read that a tide buzz can be used as a sonic welder. and when modified it can even deal in some metals.
