I don't usually leave reviews but after getting these things I have to say don't waste your money they aren't stainless steel nuts they are are stainless steel caps and the quality is terrible. They look great but when I went to put them on my car the caps came on 2 of the first 15 (I had to cut one out) so I didn't even open the last pack. I've contacted Gorilla and haven't gotten a response yet, but can you imagine being on the side of the road changing apartments where I couldn't turn? As an update I have to say the Gorilla products have great customer service, I emailed them about this and they actually called me and will be replacing them with electroplated ones so we'll see what turns out to be a replacement.
