A friend of mine used to buy the first model of any new and hot BMW. He'd know the specs better than the sales people and he spent a fortune on them.

They also spent more time in the shop with electrical gremlins than any car that I've ever seen. One of our employees insisted on a Mini, which is also BMW as their lease car. No other car we had had that much trouble. BMW is a crap brand that used to make very good cars. Mercedes is getting there. Neither of these will survive in the longer term if they don't somehow get back to their roots: making safe and reliable vehicles with good resale value. But for both companies the problems are in the same domain: they never got the hang of software.

Probably more of a gimmick than a strategy. In the grand scheme of things in cars a pretty minor one too. Replacing a panel and a bolt vs. replacing more complex components that have proprietary firmware, wiring harnesses, 3d printed/molded components with very complex design and tolerances, etc. A lot of that is business as usual across the industry.

The key issue here is that repairability is currently not really factored into the sales value of the car. That's a bit naive of course because it actually does impact the second hand value of a car. For example, MG makes nice cars but they have a bit of a reputation for needing lots of repairs under warranty. That reduces their second hand value and therefore also impacts their new value. You can get some really good deals on second hand ones. But the repairs might add up. That's why the second hand value is so low.

Lease companies buying new BMWs to lease them out to high salaried executives expect to be able to sell these things on 3-5 years later and get a decent second hand value. If the car then has a reputation for being a bit difficult and expensive to work on (like MG), that is going to reflect in the second hand price. And the lease price. Mostly lease companies just pass that on in the lease price. That works for BMW until more competitive vehicles show up that can be leased at a lower cost.

A few quirky bolts won't move the needle here. They aren't going to get rich selling them or the tools that go with them. It's just a bit of minor friction for car repair shops. If they see enough BMWs in their shop, they'll get the damn screws and tools. It's not that different than Apple using custom screws on their devices. Every phone repair shop has the tools now.

BMW used to be extremely good and very repairable/upgradeable.

They have clearly lost their way. Seems like a fundamental loss of confidence in their ability to produce leading technology, and instead feeling like they must defensively focus on blocking and extracting maximum funds from customers, both with costly "authorized-only" repairs and subscriptions for heated seats.

Sad

actually reminds me more of the "mechanics feel" part.

Lots of pros use a hand screwdriver and they never strip heads/threads/etc

And that would violate both BMWs Trademark and Patent, which at least in Switzerland could mean having to pay BMW damages and get fined for importing counterfeit goods.

Fine. But the broader point is that the customer is the product, not the owner of a purchase.

I wrote one for a test drive but then I forgot the turn signal and got pulled over.

There are many non-standard screw diameters and threads. They are often implemented for particular requirement-driven (you may want deeper threads to increase strength or vibration-resistance) or regulatory reasons (certain tariffs kick-in at specific screw diameters).

IIRC in Europe at least that doesn't work because now your third party has the defence of necessity. They didn't want to use your protected mark, but it was necessary or else their product wouldn't work, so, the protection doesn't apply.

On the contrary, they are asking for trademark dilution with this.

This is also why a lot of car bumpers have the make/model/logo impressed into the mold itself

Unlike all the other guesses here, I actually do have experience with manufacturing specialty aerospace fasteners similar in size, shape, complexity, and precision as these. These are most assuredly being manufactured on a specialty tool called a “Swissing Lathe”, or Swiss CNC machine, because that is the machine you always use to make parts like this. It is a multi-headed turret mill combined with a lathe that can continuously feed a piece of long bar stock and continually spit out fasteners. They were invented many years ago to produce extremely high precision small screws for watches, and in fact Citizen is one of the main vendors of these tools to this day. Based on my experience I would expect the cycle time for making this part to be 30 seconds or so.

Here’s a good video that eli5’s the difference between a Swiss screw machine and conventional CNC.

And here’s a video with a high quality soundtrack that shows how the machine combines automatic lathe cuts, mill cuts, and thread rolling without changing machines, swapping cutters, or re-fixturing the work.

And if you need some specialty fasteners made and have an unlimited budget I can reccomed these folks.

CNC Milled and suface brushed. I Think these screws are going to be used in some decorative Panels etc. Would be cost prohibitive to use these all over the Car.

The prototypes might be milled and/or produced via additive manufacturing (3D printing.) In production the heads are likely formed via stamping. Here's an old video I remember watching as a kid (Unfortunately quite pixelated) of the Robertson screw being manufactured which has a tapered square profile for the bit: https://www.youtube.com/watch?v=Td7GjAMAY7Y (The Acme School of Stuff was awesome for its time and still is.)

The head was almost certainly milled out of a blank made on a lathe. Something like this: https://youtube.com/shorts/Yf-twqgWZQ8

I don't see any geometry that would be hard for casting or milling, it's slightly more expensive because you can't do it in one go, but you have to lift the toolhead if you mill.

For prototypes, almost certainly with a CNC lathe. For a large scale production, I would expect them to drop forge these...

Those are end mill marks.
