Parts for your 2018 Holden Captiva 7-Wheel studs nuts

2018 Holden Captiva 7 — are wheel studs and nuts used?

Based on technical references, wheel studs and nuts aren’t used on the 2018 Holden Captiva 7. Instead, this model is built with five wheel bolts per hub. Holden’s CG Series II Captiva Owner’s Handbook (MY2018) refers to “wheel bolts” in the Wheels and Tyres section, and the GM Service Information (SI) procedures for the Captiva/Antara platform specify removal and installation using wheel bolts rather than separate studs and nuts. The Opel/Vauxhall Antara workshop manual (the sister model to Captiva) likewise shows a hub with threaded holes and bolts, not pressed-in studs with nuts.

Why no wheel studs and nuts on this Captiva? It comes down to the platform’s hub design. The Captiva 7 uses a hub with tapped holes, the wheel is clamped to the hub face with bolts. That approach is common across many GM Korea and Opel-derived vehicles. It keeps the brake rotor easy to remove, can simplify manufacturing, and ensures hub-centric location of the wheel. Practically, it just means the part people might search for as “wheel studs and nuts” isn’t applicable to this vehicle — the correct service part is a wheel bolt.

For routine servicing, the focus is on the wheel bolts and the condition of the hub threads and seating faces:

• Clean the bolt threads and the conical seats in the wheel, don’t lube threads unless a service bulletin expressly allows it.
• Start all five bolts by hand to avoid cross-threading, then tighten in a star pattern with a torque wrench.
• Recheck torque after a short drive if wheels were off for tyres, brakes, or rotation.
• Replace any bolt that shows damaged threads, corrosion, a deformed seat, or if it’s been over-tightened with a rattle gun.

Thinking about converting to studs and nuts? Aftermarket stud-conversion kits exist, but they’re not an OEM fitment for the Captiva 7. Any conversion should match the hub thread specification, preserve hub-centric location, and meet local ADR/WOF requirements — get competent engineering advice before going that route.

Popular questions about 2018 Holden Captiva 7 wheel fasteners

Does a 2018 Holden Captiva 7 use wheel studs and nuts?
No — it uses five wheel bolts per wheel. That’s how Holden and GM SI procedures describe the Captiva/Antara platform, so “wheel studs and nuts” aren’t the correct parts for this model.

What torque should be used on the Captiva 7’s wheel bolts?
The typical specification is around 140 Nm, but owners should confirm the exact figure in the CG Series II Owner’s Handbook or the GM SI for their variant and wheel size. Always tighten in a star pattern with a calibrated torque wrench.

Can the Captiva 7 be converted to wheel studs and nuts?
It can be done with aftermarket stud-conversion kits, but it isn’t an OEM-approved change. The hub thread size and pitch must be verified for the vehicle, and any modification should be checked for compliance and safety before fitting.
