They came in a set of 20 to fit my jeep. Only 19 actually fit. The one that didn't fit was designed for a smaller bar. I did a trial fit on a bike using a "pocket trick" with a torque wrench (no air exposure) to test the fit and the paint came off. Instead of messing around with repacking and shipping back, I found a real nut (but chromed) I had in the garage and covered them all with a couple coats of black VHT engine paint I had lying around. There are definitely better products out there.
