Wheel nut broke off - what to do? (help!)

[j.f.s]

Sounds almost like you work for them...?
The wheels are delivered complete with nuts, nothing you buy separately. It should thus be interpreted as a fitting guarantee on the complete package. Furthermore, it's the specially drilled wheel that determines the thread projection, not the included nuts.

But the text states they provide a fitting guarantee on directly drilled wheels. The keyword here is wheel. In plain text, they guarantee that the wheel fits your hub. Nothing more.

Then I agree with you that they shouldn't send weak nuts and they could definitely be more accommodating towards your problem. If nothing else, to protect their brand.

I've bought from them myself, and 'meh' is probably my experience.

It's of course unfortunate, but you're overinterpreting the "fit guarantees," which I'm sure more than just you are doing. It sounds catchy and inspires confidence, but it is still the buyer's responsibility to double-check and verify everything. There will always be these kinds of exceptions.
When I worked at the tire company, it was a classic with rims sold to Volvo that they didn't remove the retaining screw for the brake disc. It sticks out on these, and some rims weren't cast to fit properly. It wasn't just one who crushed the rim, I can tell you, but it's a bit similar there. You have to double-check everything even if they're supposed to fit.

I searched the site but didn't see anywhere you could check if the items fit, nor did I see how much needs to stick out for it to be okay. But I didn't search for very long, though.

But it's quite difficult as a layman to know if it requires a 9 or 7mm thread for the nut to fit? With a 100% fit guarantee according to the website, and maybe especially for Tesla, I would probably trust that the things I get are okay

one might think so, but then it's better to buy the things from a local company and have them installed by professionals who know what to look for.

Absolutely

Exactly how are you supposed to know the required protrusion length?
It's obviously also about the strength of the nut. A longer protrusion might have helped here. But it could just as easily work if the nut quality was better (and they refuse to disclose it).

The issue is that they use a much narrower nut than the original nut, to accommodate their special solution. It is only HEX 17mm fitting whereas the original is HEX 19. Additionally, the steel quality might be inferior, there's no way to know!

Exactly how should one know how much overhang is required?
It obviously also involves the strength of the nut. Longer overhang might have helped here. But it could just as well work if the nut quality was better (and they refuse to disclose that).

The thing is that they use a much narrower nut than the original nut, to fit their special solution. It is only HEX 17mm while the original is HEX 19. Furthermore, the steel quality might also be worse, which is unknown!

As a layman, it's obviously difficult. I fully understand your points, but probably this wouldn't have happened if the bolt reached a bit further into the nut itself, so it gripped more. Nuts that come with such wheel packages are based on two things. Thread and type of cone in the wheel. That's it.
The nuts themselves are quite common. They look like the classic slightly cheaper "kinesmuttrar" many sell. Maybe not the best, but probably not so bad that this should happen if all factors are met. What distinguishes bad nuts from good ones is mostly surface treatment. Cheap ones rust quickly and the chrome peels off. I've never seen or been involved with such bad nuts that something like this happens and one can categorically say it's due to the nuts.

I can tell you that the steel is as soft as can be (low yield strength). I was a bit quick and gripped a nut wrongly in the first season, and despite incredibly low load, the outermost cm of it got damaged (but I hammered it back so I could get the socket on again). As a steel designer, I know there is a difference between steel and steel. There is a range of different yield/breaking strengths to choose from with steel construction screws/nuts.

But sure, even with poor quality on the nut, it might have worked reasonably well as long as the protrusion was longer. Now, inevitably, a slight bending moment is also added to the nut in addition to the pure shearing.

Here I googled another case of someone experiencing stripped nuts from ABSwheels.
How to loosen the wheel bolts? – teslajohanssons.tips

It seems that in this case it was eventually resolved by the workshop removing the entire hub and loosening the studs from the back. Total work time was 9 hours.

Here is a similar thread, albeit Model S, but I guess it's the same solution. He ended up replacing the entire wheel hub. "The SKF hub cost just under a thousand online." I wonder if I can find one for the Model 3 for that price too.

It is possible to replace the studs in the hub, as long as you can remove the wheel, it’s usually a simple task to knock the damaged one out backward… Then position the splines on the new bolt in the old grooves in the hole in the hub, and use a nut and washers to draw in the new bolt...

Of course, it's all unfortunate, but you're overinterpreting the "fit guarantees," which more than likely others do too. It sounds flashy and inspires confidence, but it's still the buyer's responsibility to double-check and verify everything. These kinds of anomalies always exist.
When I worked at the tire company, it was a classic case with rims sold for Volvo that they didn't remove the retaining screw for the brake disc. It sticks out on these, and some rims weren't molded to fit properly. I can tell you, it wasn't just one person who crushed the rim, but it's somewhat the same situation. You have to double-check everything even if they're supposed to fit.

Exactly how should one check that the package with items delivered by the company fits together?

Fast ABS Wheels hardly manufactures its own nuts......they probably sell the same/similar stuff as everyone else from regular wholesalers. The unique thing about ABS might possibly be their own rims. It's unfortunate when things like this happen to individual customers, but if you look at it in a broader perspective, it might be a few cases per year among perhaps thousands of sold packages, and then the question is whether it's the fault of the goods or something else.........

But you said yourself that the screw length is too short. They are providing Model 3 owners with wheels where the screw length is too short. Additionally, there's a large quality variation in bolts and nuts. In my industry, these are always tested, and often they fail during testing, despite a strength certificate.

no I said that I think it is too short..........So in the end, it might very well be that they are providing all these with the wrong products. I don't know. It's probably the combination that was unfortunate..........they might have several different suppliers of nuts, and you were the first among them to get these particular nuts. All others might be driving around unsafely even though they're attached with other nuts. I've been involved in situations where rims have come off because they were held with too few threads. In that case, the threads just stripped without the nuts breaking, and the car fell to the ground.
Again, the importance of double-checking everything and questioning before using things.
But I'm still curious about the screw protrusion on the original versus the rims you have. How many turns can you thread onto an original nut with an original rim versus the ones you've got now from ABS? I haven't really seen any numbers yet, so it's just guesses and no facts from me.

Mistakes can always happen, but the handling afterward (based on what we've seen here) is 100% their responsibility.. And it seems like several Tesla owners have experienced the exact same thing, so you can't just put your fingers in your ears and pretend nothing happened....

admittedly, but it would have been better if everyone checked the matter beforehand instead of just slap it on as everyone does and deal with the problems when they arise. If everyone has the same issue and it might be due to the same thing, the problem isn't solved by mounting it and breaking it, and then complaining......
But we still don't know what went wrong either. If ts can determine that the screws become way too short with the ABS wheels in place, then we're getting somewhere at least. Then it can be bluntly stated that the combination IS unfortunate and TS should have stopped the installation. Just like everyone else .......
