DESCRIPTION
Some vehicles may exhibit corrosion of the wheel nuts. This is caused by torsional stress concentrating on
the tip of the wheel nut because of the thin and long shape of the nut, which damages the coating and
causes the corrosion. To correct this issue, the width across the flats of the wheel nuts have been changed
from 17mm to 21mm.
