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.
There are two ways to measure lug nut size:
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.
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.
Most cars have four or five lug nuts on each wheel. Some vehicles with larger wheels may have six lug nuts.
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.
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.
