Yes, the hub is identical
Same 5x105 PCD and same 56.6 mm centre bore: wheels from Holden Cruze Essence bolt on and centre on Opel Astra K without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres
Each original wheel from Holden Cruze Essence is compared with the one from Opel Astra K of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Opel Astra K (Ecrous - 12x1.50), 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.
