PCD adjustment wheel nuts, often referred to as 'wobble' nuts, these high quality closed wheel nuts have an M12 x 1.50 pitch thread, with a tapered washer to suit most aftermarket and some OEM alloy wheels and they feature the main thread slightly offset within the nut. This actually allows wheels with not quite the right PCD to be used on vehicles that were not technically designed for. For example these nuts can be used to fit wheels with a PCD of 4 x 100 onto a hub that has a PCD of 4 x 98. Obviously there is a maximum offset that the nuts can accommodate, the manufacturers state this as 2mm.
