Wheel bolts and lug nuts.
To fasten the wheels to the car, wheel bolts or wheel nuts must be used.
These fasteners are specific bolts and nuts to be used when mounting a wheel, and they come in many different thread sizes (and also various taper sizes like shape, degrees, etc., while 60 degrees is the most common) as different cars require their size, although many uses the same.
Update: See this blog post for which tools to use when fastening the bolts/lug nuts.
Wheel bolts and nuts are used to fasten a wheel to a car.
Some cars uses wheel bolts and others are using wheel nuts, for example most Chrysler vehicles use lug nuts while BMW cars often requires wheel bolts.
Here are some photos of these bolts and nuts, we start with some wheel bolts.
Both wheel bolts and lug nuts in the below image.
A single wheel bolt.
And a single wheel nut.
There are also wheel nuts with a open top, to use if the stud bolts from the vehicle wheel hub are too long for a standard wheel nut with a closed top (above image), but of course are also longer lug nuts with a closed top to choose from, it's a cosmetic choice which you like the best in that case.
The wheel bolts and lug nuts mounts through the bolt pattern holes, of course, as seen below.
Fun facts! Did you know that some sports cars are using only ONE large lug nut or wheel bolt to mount the wheel to the car? For example Koeningsegg, certain Porsches, etc.
Locking wheel bolts and lug nuts.
So, what is a locking wheel bolt or locking wheel nut? Well, the answer is simple, they provide additional protection against theft (premium wheels/rims are unfortunately vulnerable for theft) by using a unique shape to the bolt head or lug nut, which means you cannot use an ordinary 17 mm socket, 19 mm socket or whatever it might require. Locking fasteners comes with a special socket which mounts to the standard socket.
As seen above, the shape of the bolt head is rather unique and require a matching socket in order to unmount or mount the wheel.
One locking bolt or nut is used per wheel, but you might as well use more than that, to add extra protection.
We highly recommend that locking bolts or nuts are used to prevent theft, no matter what type of wheels you are using, because even if you have some old steel rims, the tires might be of high value, right?
That's it for this time.
Bolt up and get out on that road! See you!
