Dont ask, dont buy and definently dont use. Buy wheels that fit to start with.
Wobbly bolts have a cup section which is over bored to allow the bolt to sit off square with the centre of the cup. This allows the cup to sit inside the recess of the wheel bolt hole with the bolt off centre into the hub.
They are dangerous and they can come undone as they are different metals which heat at different ranges, causing a loosening affect. If they start using them on race cars, I will start using them, until that time, use the correct bolts on what surely must be the most important fastening on a car!
