Not so good for my head nuts

They were the correct size that I ordered however I had a very hard time installing them. So much that after I broke two of them trying to install them that I stopped installing them. I don't quite know at this point what plan B will be.

Look great, but takes a little work to get them on. Broke a couple trying to install, and tried to heat them to make them fit better, but now will try taking each off and sanding the original nuts.
