These nuts have been designed with a 'Floating' washer attached, which can move approximately 1-1.5 mm in a 360 degree circumference. This allows a wheel of correct centre bore size (Hub Centric) to fit several different P.C.D applications whilst still keeping the nut/bolt centralized and parallel within the recess pocket of the wheel avoiding cross threading the hub/stud.
WARNING: A qualified mechanic or wheel/tyre fitter should only carry out the fitment of these Variable P.C.D bolts.
