Not all wheels are secured the same way. Some use wheel nuts, others wheel bolts — and each plays a vital role in keeping your vehicle safe and stable. In this guide, we break down the key differences, how to identify the right fit for your car, and what drivers should know before replacing or refitting their wheels.
We don’t need to tell you that the wheels of your car play an integral role in its functional movement, in the safety of you and your passengers, in your comfort, and in the overall vehicle performance.
But did you know that they are held in place by some relatively small nuts and/or bolts?
What is a Wheel Nut?
For anyone who has had to change a tyre due to a puncture on the road, you will know all about wheel nuts and how to remove them.
These are the screw tops which clamp the wheel onto the vehicle and need to be undone with a specific wheel nut lock – typically found in the glovebox of your car.
To fit a wheel nut in place, the wheel needs to be aligned with the studs which are fixed to the vehicle. Holes in the wheel structure fit neatly over these studs, with the wheel nuts then screwed in place to hold the wheel tightly in its position.
Without the correct wheel nuts, the wheel becomes loose, and the safety of the vehicle is negatively impacted.
Which leads us to ask… how do you know what the correct wheel nuts are?
Identifying the Right Wheel Nut
The type of wheel nut used needs to match the tyre and the studs that the wheel nuts are screwed onto.
Many different vehicle manufacturers boast their own specific designs to ensure compatibility between the wheel and the vehicle itself.
What is a Wheel Bolt?
The wheel bolt system is an alternative method of fixing wheels to vehicles, using a more straightforward and flexible bolt which fastens the wheel to the vehicle.
In contrast with the nut, which appears like a cap that screws onto the end of an existing stud, the bolt is a long structure with threading which screws directly into the wheel hub.
While the wheel needs to align to the bolts and the screw holes in the vehicle, there aren’t pre-existing studs to match with the screw fitting and so there is more in the way of choice for drivers. This means that there are fewer parts to understand and focus on, when positioning a wheel using a wheel bolt.
