Find the right size of lug nuts & bolts

Choose Your Car

Are all lug nuts the same size?

Knowing how various lug nut sizes and types vary from vehicle to vehicle is critical to being able to replace one if it goes missing, damaged, or destroyed. These little parts keep your wheels and tires attached to your car, so it's important to make sure you have the right lug nut size for your specific vehicle.

They differ in diameter and length, so it's important to know the exact measurements for your car's make, year, and model before heading to the store or browsing. Ill-fitting lug nuts can cause all sorts of problems, from stripped threads to damaged lug nut holes, so be careful.

How to measure lug nut size?

There are two ways to measure lug nut size:

  • The first way is to physically measure the lug nut with a ruler or caliper. This is the most accurate way to get an exact measurement, but it can be difficult to do if the lug nuts are already installed on the vehicle.
  • The second way is to find the size of lug nuts that fit your car in your owner's manual. This is the easiest way to find out the lug nut specs, but not all manuals include this information.

If you can't find it there, try our wheel lug nut size chart for each car make and model instead. We verify and constantly update our car parts specifications database.

Do not tighten your lug nuts too tight

It is a common mistake for new mechanics and people with little experience. When replacing wheel lug nuts you should be always aware of the acceptable lug nuts torque. Usually, lug nuts should be tightened to the point where they are snug, but not so tight that you strip the threads.

Use a lug nut torque wrench to make sure you're applying just the right amount of pressure. Keep in mind that lug nut torque specs can vary from vehicle to vehicle, so always consult our lug nut charts, your owner's manual or a professional mechanic to be sure.


How many lug nuts are on a standard car wheel?

Most cars have four or five lug nuts on each wheel. Some vehicles with larger wheels may have six lug nuts.

What is a lug nut cover/cap?

A lug nut cover (also called a lug nut cap) is a small plastic or metal cap that covers the lug nut to give it a finished look. Lugnut covers are purely cosmetic and do not serve any functional purpose.

Do you need special lug nuts for aftermarket wheels?

Aftermarket wheels usually require aftermarket lug nuts because the stock ones may not fit the wheel so well. It is important to get lugs that fit your aftermarket wheels' lug nut socket size.
