They work with the idea that they have X amount of "give" or flex when they twist.Sometimes they use "torque sticks". They are about six inches long and look like extensions. They are color-coded and max out at a certain torque rating. I don't completely understand how they work nor do I trust them, but I see them used frequently in tire shops.
What about torque sticks? A torque stick is used with an air impact wrench to avoid over-tightening fasteners when installing wheels. Torque sticks work by flexing (like a torsion bar) when a torque limit is reached. When the stick flexes, it resists further tightening of the fastener. The thicker the torque sticks, the higher the torque to the fastener.
Torque sticks are useful, but they are no substitute for final torquing using a calibrated torque wrench.
I watched the video. No offense or insult intended, but the truth is, that is a terrible video - it's riddled with incorrect methods and bad information. It's a how-not-to rather than a how-to. First, you never use a torque wrench in that manner. Use your shortest extension to provide adequate clearance. Second, you never, ever use a torque wrench to loosen a bolt - it's a nice, quick way to throw its calibration completely off, after which it's a useless tool unless recalibrated. Third, when you showed hand-tightening with the large 4-way, then checked with the torque wrench, you did not show that you had tightened it accurately, Instead you showed that you had overtightened it. The immediate click demonstrated that fact. Fourth, that method is a great way to snap off a lug bolt or destroy a wheel, as most of the time damage of that kind cannot be repaired. Alloy wheels can easily be cracked or deformed at the holes. leaving them ruined, and you just showed everyone how to do just that. The entire video is horribly wrong information and bad advice, and is a dangerous disservice to the public. People unfamiliar with the process are not going to have a "feel" for how tight to tighten the bolts. In the hands of someone who actually takes it at face value, this video could result in wheel or lug failure and a terrible crash. Leaving you liable in a civil lawsuit, and responsible for damage to property or persons, or death. Possibly even criminal liability too.Is that more or less a way a person starts insulting one who took a forum members request to use a torque rachet here and bringing
Yes Have you yet to see me replace a ripped aluminum rim? they should keep to the topic this is not Harvard or Yale just some Grease monkey shop

I would highly recommend you take this video down immediately before it gets someone injured or killed, or, at the very least, their wheel or even the whole vehicle damaged or destroyed. Hopefully most people would have the common sense not to follow these instructions, but there are many out there who won't know enough to recognize it for what it is which makes it dangerous.
It may sound extreme to some, but if you disagree with my assessment, I submit that you are part of the problem rather than the solution. I have reported it to YouTube as dangerous. I have also reported it to moderators here.
no sweat. glad something pos was said lol.Hey Mr. Fish, keep on keepin' on with the videos.![]()

You want to break your hand, go right ahead. it does not take much pressure using the wrong tool to do so. that you knew?
I read what I wanted to and basically removed the negative comment off the youtube's video not because it was directed to me, because it's directed as hatred to the youtube.com rules and guidelines for your protection.
Hatred? There's no hatred involved. It's a simple warning to others that the methods you demonstrate in the video are unsafe and dangerous. So, hatred? There's no way you can logically construe anything I said as hatred. It is not possible. I'm sure YouTube will understand this quite clearly as well. That does seem to be the case so far as my comment has not been removed - it's still there.
Not insulted let me give you a 6 inch lug tool and work that.. and you still come back saying it's the wrong tool to use.
As toque tools are made to check for????
This test is for industrial use only. When conducted high end torque wrenches are used (the kind we ordinary folk cannot afford!) to verify and maintain accuracy. This kind of test is not recommended for use where a calibration test is not present. Also, your version (in the video) of this test was not done correctly. After using the large 4-way to tighten the bolt to a random tightness, you used the torque wrench in reverse to loosen it, but the very way you tightened it invalidates the test as it was at a random, unmeasured torque before you loosened it, so it did not in any way measure the tightening torque. It did click during loosening, but that only indicates it was overtightened. It absolutely does NOT indicate your random manual torqueing was accurate, only that it was more than 80 pounds feet.
Loosening Torque Test
This test is also known as the “breakaway” test. It is similar to the “first movement” method, with one basic difference. Instead of applying torque in the tightening direction of the fastener, this test uses force in the direction that loosens the fastener.
To conduct this test, take a screw or bolt that is tightened down and begin to loosen it. When the fastener breaks loose, record the torque reading. The torque value to loosen the fastener is the approximate torque that was applied to the joint. This method is considered the easiest to perform, but it may not always correlate to the torque applied to the joint.
From low-cost tools to sophisticated fastening systems, all assembly equipment need to be audited. The objective is to verify accuracy and repeatability performance goals are being maintained. Eventually, torque tools begin to drift out of tolerance. An auditing technique to detect and prevent fastening failures is vital.
Thanks for that video. I get it now. I was definitely taught in high school to use as little extension length as possible, as it would throw the accuracy off. What I know now after more research is that, while it definitely does make a (very slight) difference, that difference is so minute as to not make a measurable change as applied here. So, in essence, I was taught wrong. Not that it has made a huge difference in my work, but at least now I know that concern is unnecessary. It was thought, and taught then that you should not use an extension longer than needed, or in any case longer than 4-6." Every mechanic I knew swore by this, including race crew people. Luckily it didn't hurt anything, it just imposed an unnecessary limit. But now I know better, so thanks to all who provided information on it.Kinda long, but interesting info. Go to about 4:30.
Does an extension affect a torque wrench? | Helping you work smarter not harder
Socket extensions do NOT affect the accuracy of a torque wrench. Every action has an equal and opposite reaction; newtons third law. If you turn one side of the bar, the other end must have an equal affect on the other end. A bar under torsion (twist) acts like a spring. The stored energy inrtstools.com
