Not only did these nuts not fit properly (although they were confirmed to be suitable for my application), they also damaged my aluminum wheels. The threads are fine, but the base diameter of the nut is too small, causing them to sink into the wheel where the nut should be tight. I tightened them to factory spec and the bolts went right through the end of the nut! They also rusted terribly after only 1 week on my truck. Couldn't even get a refund for them. Complete garbage. Avoid at all costs!
