Torque Test Channel - open-end wrench testing

[American Locomotive]

Don't get me wrong - I rag on Torque Test Channel all the time, especially on their impact comparisons and how they try to extrapolate torque values. That's why I appreciated in this video that he just reported the PSI achieved on his test rig. Even then it could still be improved by a load cell directly measuring the applied torque.

I'm super critical of their methods, and I could find very little wrong with this test. Like I said earlier, this is a really great test of open end wrench geometry. Poorly designed (or traditional) wrenches concentrate a lot of stress on the corners of fasteners. It doesn't matter if the bolt is made out chocolate or steel. If the wrench can distribute its force more on the flats, than the corners, it's going to work better on ALL fasteners.

This isn't a test of ultimate wrench strength. The very worst of the wrenches here did experience spreading of the open ends, which the soft nut helped to mitigate. That's more of a metallurgy thing, than a geometry thing (unless the wrench had a ridiculously thin cross section for whatever reason). But shooting an XRF gun at the wrench isn't going to tell you much besides what alloy it is. Things like hardening, heat treatment, cryo treatment (if applicable) and even the forging process itself all contribute tremendously to the strength of a wrench.

if that’s not good enough for you then you’re being deliberately obtuse or Expecting him to be NIST entirely out of pocket, and you’d probably still say the same thing if he actually did that

He is doing this as a business. Let me say that again, he is doing it for the money that YouTube is paying him for views. He is not investing in his business and is not producing a quality product.

Just as everyone is looking at the quality of the wrenches, you have to look at the quality of the test as a viewer.

I'm not going to discuss this further.

I, too, recently discovered ANSI standards cost about $90 a piece. Which immediately made me question their validity if they are just in it for the $.

Fellow belly achers. If it's so easy to Monday quarterback holes into this experiment, please make a new thread with the results from the true ideal testing set-up. From what I've read it should be super easy and obvious how to do it better and everyone will agree with you that you chose the best way.

Do you feel like you overpaid for the video?

They spend a lot of money on tools, hardware, and testing rigs, video and production equipment, and their time. I'd call that investing in the business.

Quality product? Well that's subjective. Some people think Ford is quality. Some think it's trash. Ford still invests in their business to produce the vehicles.

Looks to me like he simulated a compromised fastener as best as he could and cranked on them to see which wrenches grabbed the best.

Kinda like we all do before busting out the vice grips and/or torch and/or big nasty and/or gasoline and lighter and/or nearest cliffside without obstructive railing.

It wasn't a test to see which wrenches take the most torque before snapping, it was a test to see which wrenches bite a fastener best before making your day longer and more oxy/acetyleney.

You still have not identified any valid reasons why this isn't a quality product.

The premise of his video was simple: Which open-end wrench will grab a fastener and apply the most torque to it before slipping. It's a real world use case for millions of wrench-wielding people every single day.

The specific alloy, heat treatment, dimensional tolerances, forging techniques, the jaw spread or whatever of the wrenches are simply not relevant to the parameters of the test. He is not setting out to find out WHY certain wrenches grab better than others - simply which wrench grabs the best. TTC is not an engineering channel.

It'd be like asking a vacuum cleaner reviewer to start going into in depth on fluid dynamics, types of motor windings, impeller design and more. It doesn't matter. Which vacuum ***** harder. Done.

He (the narrator) is an engineer that has been hired by Astro Pneumatic since starting the channel. One of his co-creators is a mechanic. Every cent of income they made in the first year went right back into their videos.

We are. Your arguments against them are vague and nonsensical.

That's for the best.
