Find the right size of lug nuts & bolts

The lug nut size is one of those aspects that make a big difference for the car because it can determine how the car will be able to move. There are different types of lug nuts, and each one has a specific purpose. And how can drivers know which option is right for them and their vehicle? Read further and you will become a specialist in lug nut sizes, wheel fasteners, thread pitches, and other stuff.

What are the different sizes?

When a driver looks for a new set of lug nuts, they will come across different designs and sizes. So, the common lug nut sizes are often 17 mm, 19 mm, and 21 mm, while less popular ones tend to be 22 mm, 23 mm, 17.5mm, or 20.6 mm. In most cases, such vehicle types as sedans and small pickups use 17 mm nuts, while larger vehicles like SUVs go for 19 or 21 mm ones.

Note, that if the lug nut size would be more than needed, your vehicle might have some serious problems. The lug nuts that are too big will be difficult to torque to the car’s specifications, and this can cause them to loosen over time. Also, if the lug nuts are way too small, they might not provide enough gripping power and shear off under load, which can be extremely dangerous.

Finally, when speaking of thread size, you should know that for a certain bolt pattern, there would be a special thread size and pitch. Thus, common threads per inch (TPI) sizes are as follows: 4, 4-1/2, 5, 5-1/2, 6, 7, 8, 9 ,10 ,11 ,12 ,13 ,14, 16, 18, 20, 24, 28, 32, 36, 40, 48, 56, 72, and even 80. So, drivers should know which one fits right for their auto, as it all affects the riding.

What figures to pay attention to?

When selecting the right size of lug nuts & bolts, drivers may find out some additional information like center bore (or hub bore) specifications and wheel torque characteristics. But do you really need them or do vendors simply want to confuse you? Well, all these specs are really important, cause as we mentioned above, only a certain wheel size will match peculiar center bore and wheel torque parameters.

Inter alia, in case the hub collar's diameter is greater than the hub bore, it will be impossible to install the new wheels. And if vice versa, fitting it will be difficult because there will be unwanted diameter variances.

As for wheel torque and fasteners, only certain torque specs will ensure safety while driving. That is why you need to be attentive and use all the necessary measures to get perfect lug nuts & bolts!


Don`t be afraid of all those numbers and terms, everything is simple! You just need to know the size of your lug nuts and bolts, and that is it. With our tables, you will easily find out what product will perfectly go with your personal vehicle!

Lug nuts terminology and definitions

What is thread pitch?

Thread pitch is the measure of how many threads are on a screw or bolt. It's an important concept when you're trying to find the right size of lug nuts or bolts for your car. If you have a metric thread pitch, it's relatively easy to find the right size. All you need to do is measure the distance between two adjacent threads and compare it to a chart.

How important are wheel fasteners?

They can be either wheel bolts that thread into hubs or a combination of hub-mounted studs and removable nuts. Usually, wheel fasteners determine how your vehicle handles on the road. If they're too loose, your car will wobble. If they're too tight, your car will shake. Either way, it's not a pleasant ride.

Do hub-centric rings have to be exact?

Make sure that the spacers you use fit perfectly with the wheel center bore and wheel hub. This will ensure that they are the correct size and will not cause any problems. You can do this by using spacers that are the same size as the bore and hub, or by using hub-centric rings to make up for any difference in size.

Do all lug nuts fit any car?
