If your nuts are coming loose / coming off, there is something else wrong. The serrated nuts work perfect unless something else is wrong.

The most common overlooked points when wheel nuts are coming off are:

1. One or both wheel bearings in the hub are seized or in poor condition.
(its normally the inside one that goes first).
2. The steel crunch spacer between the bearings is either missing or has been damaged. (If you are running a very old version of the car you might have the old alloy one in here, it's yellow, but I'm pretty sure your car should have the steel one in.
