what size are the lug NUTS in millimeters. I was given a set with my new alloys 12 mm.'s,,,they fit sort of but not quite right. I think I might have to take them back.

thank you

 

I'm sorry I don't have the answer to your question. But I do know this. Either they fit or they don't. Sort of fit would have stripped you bolts.... I'm sure they fit if you were able to put them on... Maybe we could help if you could be more descriptive on what you mean by sort of fit....

Thanks! I figured out what happened. The place that sold me my alloys gave me 20 lug nuts, size 12mm x 1.50
they should have been 12mm X 1.25.

The 1.50's could be turned onto the studs about a turn or two, before it tightened up, but by that time, a lug had been stripped. Fortunately only ONE!!!
