Sorry for the bit offtopicness - it's a mechanical question, no need to start a new forum ;-)
Is there any dissasemblable equivalent of these? Whats the english word for them?
I have a connection of two pieces of metal, which will rotate around the connection. But I wanna be able to dissasemble the connection. I don't wanna use a screw, because it would most likely untighten after a few movements.
