I'm relatively new at breadboarding. Maybe I'm missing something. I find online, male headers that are meant to mount in a PCB that are say 6 mm pins on one end and 3 mm pins on the other. Is there nothing similar that is 6 mm and 6 mm that I can use to mate a breadboard female socket to a female socketed ribbon connector? Can't find such a thing. Maybe it's not called a header. Would appreciate any help.
