Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Saturn Astra 5 trou (M12x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
