The author seems to lack basic knowledge about bolts/studs and economics. Each bolt/stud is made to meet specific requirement for different applications and the price is based on manufacture cost and profit. That is why bolts/studs need different specifications. The tests carried out in the video have only shown one of the bolt/stud characters - tensile strength. And only the $0.5 bolt and BMW stud have specification on them, 5.8 and 12.9 respectfully. The 5 means a tensile strength of 500 MPa and 12 stands for 1200 MPa. Lets just forget the .8, .9, and MPa for now. The BMW tensile strength should be 1200/500 =2.4 times of that $0.5 bolt. As shown in the video, the $0.5 bolt needs 3857 kg to break, then the BMW should be able to take 9257 kg instead of 5569 kg. So, it could be that the $0.5 bolt is over spec or the BMW is under spec. However, the story should not stopped here. Since BMW is specifically designed to keep all off you expensive engine parts from flying apart, tensile strength is not the only requirement. The yield strength and thread accuracy are equally important. So, it is possible that the BMW may cost more than $50!
The Americans always troll Chinese goods as cheap(implying it is poorly made), but they never mention that Chinese goods provide superior value. The American trolling proves that Americans are either unappreciative or racist ideologues.

From the statistical point of view, I don't know what you want to express in this video. There are specifications marked on the screws. There are many specifications. I saw 5.8/8.8. For example, if it is marked with 5.8, it actually means the tensile force is 520 MPa. As long as it reaches this, it is qualified.

It is stupid to test different hardness bolt and make a comparison. There is no free lunch. You will have to pay higher price for a higher hardness steel, It is a fact that China can make a strong bolt as well with a much cheaper price than the Western.

When you buy something from a Chinese factory, they make it to the standard that you're after for a certain price. If you bought something cheap then you've opted for lower standards. That's why these studs, toys, iPhones, high speed rail and sex toys are all made there.

Compared to the price, the one made in China is the best one. You can imagine 0.5 = 3857kg, if i buy 3 bolt to use it instead, the loading capacity will be 3857x3 = 11571kgs = USD 1.5 only.
Sorry, it wasn't apples to apples test. because the white one with code 5.8 is ordinary iron and the black one with code 12.9 is steel. so this test is not fair

Thanks God,Iswear that with a quick glance I can see the difference between the weakest and the strongest bolt ,and the hydraulic press make it more clear.
Known that about bricks since I was a child, my dad was a farmer and also a carpenter and mason and he always told me that old brick were stronger than new (back in the 60's 70's 80's he would buy tons of old used brick that had old cement on them and have me sit on a bucket and clean piles of brick of old cement and he would later reuse them to build walls on homes. The old cement would crumble off of the brick using a masonry hammer and even rubbing two of them together the cement would come off when cleaning them but largely the brick would hold together, the brick gets stronger with age as long as they are sound and still whole. That is why if you see a brick wall with a crack in it from the house settling the crack will almost always be in the cement and not the brick.
