OK, I'm stupid and admit it but are all 12mm lug nuts the same?

Sorry but I bought a set of Boyd Smoothie II wheels from a guy. Of course those had 7/16 - 20 lugs. I need 12mm for my fronts since I've done the 1LE upgrade on my Trans Am. I ordered some 12mmX1.75 inch bullet style lugs from an online source but they DO NOT fit.

Are there different thread pitches in a 12mm lug?

The metric lugs you need are 12mm with a 1.5 pitch.

Thanks! That's what I was looking for.
