I didn't realize there were 3 red studs in the set. I found it interesting because in every case I can think of I mostly need an even number of fittings. If you need red fittings that are listed as: 3 x 7/16"-2, you can verify that they are in fact 3 x 7/16"-24. (last character missing from ad) Other than that, I got what I paid for and they look like quality hardware.
