I don’t believe so. Both pins came threaded with mine, that pin there in your photo (on the left) doesn’t look familiar to me. Both came looking similar to the one in my [attached] image, except the squonk pin, naturally was hollowed out (I can’t seem to find the box I last put it in to include in the photo, but it looks just like the one on the right in yours).

The only thing I can think of (that is, the only thing that makes sense for the situation) is maybe they shipped that one accidentally with a pre-machined pin?
