Parts for your 2013 Holden Colorado-Wheel studs nuts

2013 Holden Colorado wheel studs & nuts

Wheel studs and nuts are absolutely relevant to the 2013 Holden Colorado (RG). Technical references such as the Holden/GMH RG Colorado workshop manual and owner’s manual, plus the shared Isuzu D‑Max platform documentation, specify a six-stud hub using conical-seat wheel nuts. The RG typically runs a 6x139.7 mm PCD with M12 x 1.5 studs, confirming this model uses studs and nuts rather than wheel bolts.

On a 2013 Colorado, the wheel studs are the fixed threaded pins on the hub, and the wheel nuts clamp the wheel to those studs. Their job is simple but critical: keep the wheel centred and clamped with the right tension so tyres wear evenly, brakes behave, and the ute tracks straight. When they’re in top nick and torqued correctly, they spread load evenly across the hub and help prevent vibration and wheel-off incidents.

As part of routine servicing, it’s smart to give the wheel studs and nuts a once-over. Look for cross-threading, corrosion, stretched threads, or any signs a nut is grabbing or binding. If a nut won’t run down smoothly by hand, something’s wrong—stop and inspect. Avoid lubricating the threads unless a manufacturer bulletin for your vehicle explicitly allows it, torque figures assume clean, dry threads. A light wire-brush to remove surface rust and grit is fine, but don’t remove metal from the threads.

When refitting wheels, use the correct conical-seat nuts for the Colorado’s wheels, and always torque in a star pattern with a calibrated torque wrench. After tyre rotations or wheel work, re-check torque after 50–100 km. If the ute tows, carries heavy loads, or sees corrugations, add more frequent checks to the maintenance routine.

• Replace studs if they’re bent, cracked, or the threads are damaged or stretched.
• Replace nuts if the cone seat is gouged, the hex is rounded, or cap-style nuts swell or deform.
• Stick with quality OEM-equivalent studs and nuts, correct M12 x 1.5 thread, and the proper seat profile.

Press-in stud replacement usually requires removing the wheel and brake components to access the hub flange so the old stud can be driven out and the new stud drawn in square. It’s a straightforward job for a workshop and worth doing in pairs (or as a set) on the same hub if wear is consistent. Correct torque and clean contact faces finish the job—keeping that Colorado safe, tight, and ready for the next mission.

FAQs

What size are the wheel nuts and studs on a 2013 Holden Colorado?
The RG Colorado generally uses M12 x 1.5 wheel studs with conical-seat wheel nuts on a 6x139.7 mm stud pattern. Always confirm against the owner’s manual or with the VIN, especially if wheels or hubs have been changed.

Using the right thread and seat type matters—a mismatched nut can damage the wheel seat, loosen off, or make accurate torquing impossible.

What torque should the wheel nuts be tightened to, and in what pattern?
Use a star (criss-cross) pattern and a torque wrench. Refer to the Holden manual for the exact figure for your trim and wheel type, many RG Colorados are around the mid-130s to 140 Nm range. Re-check torque after 50–100 km following wheel service or rotation.

Avoid rattle-gunning them to death—over-torque can stretch studs and distort brake rotors, while under-torque risks wheel movement.

When should wheel studs or nuts be replaced?
Replace them if threads are damaged, nuts don’t spin freely by hand, studs are bent, or after a known over-torque/impact event. Also replace if conical seats are pitted or if cap-style nuts have swollen.

If one stud has failed due to corrosion or stretch, it’s wise to inspect the rest on that hub and replace as needed so clamping force remains even and reliable.
