A pile of "Zapfen" pieces.

What are these pieces called in English? Google translator doesn't help in this case...

1 Answer 1


The LEGO Pick A Brick store lists them as connector pegs (or, more simply, pegs) although they are more commonly known as pins in the fan community1.

The black ones have added friction for holding things together, while the light gray and beige ones are smoother and allow pieces to rotate, for example tires or beams.

    I can't bring myself to edit this, so I'll just critique. I have more often seen those refered to as "pins" than "pegs". Just a suggestion. Commented Oct 26, 2011 at 22:56

    LDraw uses "pin" consistently, which is why it's more used by fans, but LEGO does indeed call them pegs (with less consistency, considering the 1 1/2 is a "bush")

  • @Joubarc: Ah, I was wondering where the term "pin" came from. Commented Oct 27, 2011 at 12:30

    At the time LDraw was started, internal LEGO names weren't publicly available, so James Jessiman had to start from scratch. I feel that he, and the ones who continued to expand LDraw after him, have done a way better job than LEGO; but on the other hand LEGO had no real reason to use an English-coherent naming scheme.
