OEM lug nut vs. aftermarket #4711783

A few months ago I decided to buy a set of OEM take off wheels to mount my three season tires on.



Before finding the wheels above I ordered a set of lug nuts online from mazdashop.ca run by Scarboro Mazda, a dealer in the city. Little did I know the wheels would include another set of lug nuts and also a set of wheel locks.






The lug nut on the left ordered online appears to be an aftermarket part distributed by Fastco, of Fast Wheels, PN 60022A. The one on the right was included with the wheels, taken off of a car before delivery to the wife of a salesman at Airport Mazda of Toronto, who upgraded to a set of Mazda accessory black wheels and lugs. I never even bothered comparing the two until today. Barely even looked at them until now. The ones ordered are past the return date.

My first instinct is to stick with the shorter OEM lug nut. Any advantage to the other one or should I just sell them off?

The lugnut on the right is the factory B002-37-160B lugnut.

I would only use the factory lug nuts.

Check the fit first. The factory ones might be too short. Also notice the ordered ones have a much more robust seating area. Looks to me you might have to use a different wrench size for the ordered one. Do the test fit and you’ll know which one you want to keep.


If you want the job done right......do it yourself.

The ones on the left look like they have more thread, more universal longer chamfer too. I would use the right if they came with the wheels. The steelies I bought came with their own lug nuts for the SE and that is what they used. I received the take offs bagged and a bag full of the lugs.

I have actually had better luck with after market lug nuts.

Dont all car wheels "take off"?

If not, I suppose that might explain my having trouble with some of them.

You only need around 3 threads to engage the stud for the nut to safely reach it's max clamping force so if the shorter one fits use it

When someone buys a new car and immediately removes the wheels/tires they're called "take-offs."

The ones on the right look just like the OE's on the Mazda3 in my sig.
The ones on the left look as if they may, wink "Look Real Sharp" sticking out just that little bit. Try both!

The short ones are MUCH harder to get started over the threads with your finger tips.

So second-hand but unused wheels. OK, makes sense, just never heard (or noticed) the phrase before.

You need a min of 1.5x of the stud/bolt diameter for max strength. For a 10 x 1.25 mm stud it would be about 9 threads to achieve the 75% minimum.

I'd like to see citations to your sources. My experience differs from both of you, (between). In a prior job, we performed tension tests on fasteners for our production. We found that with high strength fasteners (socket head capscrews) less than 1 diameter was required in a conventional steel "nut" to break the male threaded part in tension. About 1.5 diameters were required in a 6061/6063 aluminum nut. These capscrews were in the 180,000 to 200,000 psi tensile strength, LIKELY higher than wheel studs. What are typical wheel stud specs; I'd guess 110,000 psi?
