Which end of these do I solder?
knotlogic:
This is probably a very dumb question, but which end of these turned pin headers is meant to be soldered into my PCB and which end is for plugging into other parts?
I picked up a bunch of these cheap for proto boards that get plugged into breadboards. I was finding that regular square pins were a pain to plug in/pull out of the breadboards I have and was worried about breaking something.

I don't know what's the name of it in English, may be the end look like "stepped shaft"?

Honestly, as a native English speaker, I'm not sure how to describe it either! The bit on the right?

They’re interesting headers...
They look like they’re probably intended for wire wrap on the shorter ‘rough’ end.
That’s the side I’d solder on, and leave the smooth ‘round’ pin for the breadboard.

Not wire-wrap posts. All wire-wrap posts are square so the corners dig into the wire.
The side with the larger diameter is for soldering.
The side with the smaller diameter is meant to plug into an IC socket.
