Probably would have been the choice of armor for the ultra ultra rich if gunpowder was never invented.

Or it could work even better as a mele weapon due to its lighweight characteristics.

@@helium-379 Titanium doesn't hold an edge well. Its too soft for edged weapons, steel in this regard is better in everything except weight

This.

Agreed..

No lo puede hacer porque no es la forma correcta de hacer ensayos de rotura de materiales; incluso las maquinas especificas a tal fin realizan la curva carga/deformacion/rotura

Russia has the best titanium in the world... what they use on their spacecraft is the best of that best. The Soviets at one point had a whole giant vacuum fabrication facility to make titanium submarine hulls... it was a giant waste of time/resources but the engineering & fabricating processes still make them the best in the world (like Taiwan with chip production... wherein the most bleeding edge becomes almost Guild Master/Alchemist that can only be reproduced within those labs by those masters who pass on this unlearnable aspect to the head apprentices.) Same reason why everything collapsed in America cause those original labs/fabrication facilities with those old masters were shut down and they have to be essentially built from the ground up again

This so can some do that for us in the comment section

Exactly which makes the tests pretty much useless..

Glad that someone else noticed that 😮 You should always double check everything especially if you get a result you didn’t expect, make sure that it wasn’t a fault of your testing.

There are definitely methods ASTM ! I believe it was American Standards Testing Materials

Bolts are not designed to be used in shear, that’s what pins are for. If they do get used in shear, they should be used in a double shear at the minimum and only the unthreaded portion of the fastener otherwise the bolt will fail at the small diameter in the bottom of the thread root.

​@@skullfracture2exactly

way back now but one of the things they taught new crew chiefs going into the US military was the different forces applied to fasteners, structural components and what those forces look like in action.

Every technology lab has extra equipment for pulling or shearing forces and doesn't play in the garage with old press lol these are standard tests in the industry

*shear

Would also like to see how much each one costs.

maybe he just made a mistake?

Yoooo was confuzzled too man

Agree, it's a bit chaotic.

Same observation... Ruins the video for me. Still fun to watch tho

Yes. It was extremely confusing.

Exactly. The shear strength of the bolt and 2 components is related to the clamping force

Idk if the thread pitch was even the same. Same torque value to to bolts with different thread pitch results in different clamping force.

@@thedarkmage7373 I didn’t even pay attention to that. Valid point.

Project Farm vibes from this comment

Actually you'd also want a test with their rated torque for each class. Over or under torquing per the material would give incorrect results

Both of these bolts are Class 5.

Ha, agreed, if I had a hydraulic press and load cells this is exactly wghat I would be doing at home!

Came here to mention this

Exactly…

Agree, came to say the same.

It's not friction, it's applying the proper preload for the fastener to perform as it's designed to. That said this entire "test" has so many sloppy variable that it can hardly be considered reliable. XD

...so does the wallowing out of the holes after each test putting the different bolts in different shear and bending situations...OK vid for a goofy comparison but must list the type and grade of the bolts correctly - so thumbs down

This is the absolute correct answer. I've worked with aerospace stuff and everything boils down to the exact required strength to weight ratio. No overkill can be afforded with them otherwise they wouldn't make it off the ground. Everything is calculated down to the nm

They were weighted at the beginning of the video FYI

In other words for construction builds Steel whilst having Chinese Titanium bolts at vital parts is beyond plenty

You answered my unposted question very well, and I appreciate that. Thank you!

@@mengguangwang not the chinese bolt.

I agree! A fine thread pitch allows for more thread contact and in turn more strength.

Also depends on where the point of failure is. Most likely at the threads. Finer threads aren't as deep therefore cross-sectional area will be larger.

I have used inconel X-750 for a forging die ejection pin mechanism. All imported from China. It worked beautifully. Toolig lasted for nearly 2 years in production. The pin it self was 16 mm in dia and 150 mm in lenght. Die operated at 500 C. had cooling and heating cycles too. Best part, the pin was 1/4 the price an American company quoted me.

Yes, I'm working as an Engineering staff, and we design machines, and yes in drawings, the plans, we use diameter 7 for a bolt of M6 for the same issue you've stated

It's a useful point that instead of going up a fastener grade simply go to the next diamater. It's pretty much an axiom saying that if breakage occurs then the fasteners were not enough for the load ;)

Days of 12.9 class bolts on cylinder heads are gone. Most cars of current century use 8.8 class bolts for cylinder heads. Torque spec is close to yield limit of bolt, so bolt acts as a spring and provides more consistent clamping force under different temperature related expansions of cylinder head

@@el_kuks "Stretch bolts" that aren't supposed to be re-used.

If a bolt is stretched it is a failure and should be binned. It will no longer have much strength.

I came here to leave a similar comment but found yet again, great minds think alike.

The bolts that have a full length thread are called set screws, bolts are partially threaded

for sure

He also used the threaded portion of the fastener which is slightly smaller and weaker

Truly unfair comparison. Space bolt had washers (clearly softer metal) and a nut adding leverage against bolt. Fastening nut should be flush as with chinese titanium bolt.

A bloke I knew worked for Scania (trucks) and he kept some bolts and stuff. You could put a spanner on those and screw them into the appropriate sized hole in steel and not bother tapping a thread first! They don’t rust and you can’t weld them (accidentally got too close to one bolt but the weld didn’t take).

@@einundsiebenziger5488 Good thing you chimed in. People must have been so confused by my typo.

​@egoequus6263 i was very confused I'm glad he explained what you were trying to type

Thought about it too.

Nothing in this video is purported to be indestructible. You need a better grasp on reality.

@@East-somewhere i just claimed they were 'seemingly' indestructible...nothing is indestructible...there is always something bigger, and stronger, or smaller and more pervasive...i prefer to not grasp reality at all since the fundamental state of reality is to always change.

@@East-somewhere You need a better grasp on a personality.

@@East-somewhere nice gaslight. my mang said "seemingly." dont ever invite this edgy clown to a party.

He is testing from what the label says., what’s the best grade …………..?

These bolts are Class 5.

Also strength to weight ratio

And corrosion resistance.

And match thread pitch

Torque doesn't appear to be necessary since they're pulling against a nut and the threads, not 2 flush plates.

Thx, just wanted to write that! That's a very crucial factor, as well as the surface condition of the connecting plates.

I doubt that would matter. this seems like the type of guy that didn't even match thread pitch.

Thats not how titanium works, titanium is lighter than steel, but similar strength, the aliexpress bolts arent oure titanium and have other alloys in them to make it cheaper to produce, but they are about the same weigh as steel, not titanium, making them useless

Probably optimized for weight VS optimized for strength

Nasa still thinks light "travels". What do expect from them? They need a bit more Einstien to wake up.

not a true test, need to have the same spec, same weight, etc...

@Baldspot How old are you ? 100 ? 😅

@Baldspot My dad was born in the 50's and he never heard that "Made in Japan" meant junk. Although you are right, the West underestimate China way too much.

I think that quality itself isn't necessarily the issue when the product in fact matches the description of the seller on AliExpress. The problem is that regulation on such platforms is often bad, so there is no guarantee that a titanium bolt is indeed made of 100% titanium.

Wow what a surprise that fatmericans are xenophobic racist twats.

@@TempAccount358 That's true that many specifications are overrated in a wide variety of products sold there.

I am guessing titanium would suck literal engineering balls in that bend test. It would take PLENTY to bend it but it wont bend much

ты прав. Привет из Бразилии

Well, weight is very important too when you want to make flying or space screws :)

95%

I felt like it was a weight off my shoulders to be honest!

High G stress and atmospheric friction HAVE ZERO to do with anything regarding these bolts. In fact high G stress isnt even a thing regarding mechanical fasteners. Its got to do with a persons ability to withstand high G's. Atmospheric friction..lmfao you dug deep for that nonsense. We dont engineer nor test bolts factors that do not apply. Ask me how i know.

​@@IOD_I'm curkous how do you know?

i think it is used due to it has less air restriction.

In the picture of the clip was no space shuttle but the soviet version.

I think it's not the head type but the grade of titanium used. Regardless of what the the tightening interface is it's more that this will be the same material type.

and if your measuring things equally, using a spacer changes the stretch of the bolt .

Yeah, this guy is just checking the numbers. Also those numbers are what the manufacturers are sure their product can handle, not what it will.

@@SoMuchFacepalm does these numbers indicate the tons it’s purposed to handle? I don’t really get it, not enough information

The beauty of steel and alloy products are their tensile strength. If you could hold onto it, several people could hang from a coke can, though one heavy foot is enough to crush it. Of course, concrete is the opposite, which is why they are a brilliant construction product when combined.

High quality steel with the right hardness is still stronger than the best titanium alloy, titanium is used for weight reduction and corrosion resistance without giving up to much when it comes to strength.

@@andreasfjellborg1810 You are right. my boss at a titanium forging plant used to say "CP-Titanium is only as good as 316 Stainless in strenght but with much lower weight. There are stronger metals, such as nickle alloys that will beat titanium any day in strenght.

Mother Fucker this was the most unscientific test I have ever seen. The dude didn't match thread pitch or applied torque equally along all tests. Know how a bolt works before testing them.

Son, Not true. there are 26 grades. Plus multiple custom grades and alloy systems depending on the application. But 5 grades are basic available to the laymen.
