Parts for your 2015 Holden Commodore-Wheel studs nuts

2015 Holden Commodore wheel studs and nuts

Based on Holden technical references — including the VF Series Owner’s Handbook, GM Holden Service Information (workshop manual), and the Genuine Parts Catalogue — the 2015 Holden Commodore (VF) is built with five pressed-in wheel studs and matching wheel nuts on each hub. Wheel bolts aren’t used on this model. The platform runs a five-stud pattern (5-stud PCD), and factory hardware is designed for hub-centric alloy wheels.

On a VF Commodore, the studs and nuts do the critical job of clamping the wheel firmly against the hub face. That clamp load is what keeps the wheel centred and secure while coping with Aussie and Kiwi roads, towing, and the odd spirited on-ramp. The studs are pressed into the hub from behind, the wheel slips over the studs, the taper-seat nuts draw the wheel up square to the hub spigot as they’re tightened. Most factory wheels use a 60-degree conical seat nut, and many variants run an M14 x 1.5 thread — always confirm against the vehicle’s handbook or parts data by VIN before buying replacements.

As part of regular servicing or tyre rotation, it pays to give the wheel studs and nuts a once-over. Look for damaged or stretched threads, rusty or pitted studs, and any cracking or galling around the nut’s taper seat. If a nut’s chrome cap has swollen and the socket won’t fit properly, replace it — rounded nuts and over-tightened hardware are a common cause of roadside headaches.

When refitting wheels, cleanliness and correct torque matter. Keep the hub face and wheel mounting pad clean of paint build-up, dirt, and corrosion so the wheel sits flat. Tighten the nuts in a star pattern using a calibrated torque wrench. Follow the vehicle’s stated specification in the Owner’s Handbook or workshop data (many VF models specify around 120–140 N·m). Avoid lubricants or anti-seize on the threads or seats unless a Holden procedure specifically says otherwise, as it can alter clamp load.

Replacing a damaged stud? Press it in square from the rear of the hub — don’t try to pull it in with a wheel nut. Fit quality, like-for-like studs and nuts that match the thread, seat style, and grade. After any wheel-off service, it’s good practice to recheck nut torque after 50–100 kilometres of driving.

• Inspect at each brake service or tyre rotation
• Replace any cross-threaded, seized, or necked studs
• Use the correct taper-seat nuts for factory alloy wheels
• Hand-start nuts, torque to spec, and avoid finishing with a rattle gun

Popular questions

What is the wheel nut torque for a 2015 Holden Commodore?
Always follow the value shown in the Owner’s Handbook or service data for the exact variant and wheel. Many VF Commodore models specify about 120–140 N·m. Use a torque wrench, tighten in a star pattern, and recheck after 50–100 km.

How can someone tell if a wheel stud needs replacing?
Warning signs include stubborn nuts, visible thread damage, a stud that spins in the hub, or a necked (stretched) section near the base. If the nut’s seat is chewed up or the chrome cap has swollen, replace the nut. Any cracked, bent, or heavily corroded stud should be swapped out immediately.

What stud pattern does the 2015 Commodore use?
The VF Commodore uses a five-stud layout. When choosing wheels or brake kits, ensure the stud pattern, centre bore, and nut seat style match the car’s OE specs, and always dry-fit to confirm clearance and seating.
