I just use the original lead mallet which came with the car, never had an issue with it.
If you are that cack handed you actually manage to damage a wheel spinner or wheel whilst changing it, are you actually safe to be on the road.
Changed a wheel on the side of the M5 once, all of 10 minutes work, much to the annoyance of the womble who turned up and wanted the car towed off the motorway

Someone else will know for sure, but I believe the rule is that you cannot change a wheel yourself on the hard shoulder, and must call for recovery?
