Torque wrench

For the extension you are talking about, it doesn't change a thing. The extenders that do change the torque driven to the fastener look like this:
EN-49191 Torque Wrench Adapter

If someone tells you a one foot extension or any length extension that looks like this, says it changes the torque, they never took a physics class.

I'm sorry if you consider me less educated than you, but, I had a testing machine in my school that would prove you wrong.

Don't take it personal, he treats everyone that way, on every subject

The extension could me a mile long and the torque would be the same.

Greatest form of compliment coming from you of all people.

Well, this is my last post so take it anyway you want. You are wrong and need a chill pill.

LOL....if the extension reduces your torque, that means a long bed truck produces less torque to the rear wheels than a short bed truck because the driveshaft is longer...hilarious!

Chew on this, if all extensions are the same, metal the same and quality of metal, temper, density and such, how do they make a torque stick work in different amounts of torque? Extensions twist, but, that might be to much for you to comprehend. As for all your other comments, I call BS on you. I can not understand people like you and I am through. I apologize to everyone I have offended and I will never post again.

Torque sticks will only work with an impact wrench because it is a dynamic load and not a static load. The torque stick responds to the impact and twists.

I really don't care if you believe that an extension changes the torque. Just clarifying in case other people were going to believe it.

BTW, torque sticks are notoriously inaccurate. If someone uses one at a shop, have them do the final torque with a torque wrench after they use one that is lower than the final torque

Look at this video if you really want to see what extensions do:

One other tidbit about using torque wrenchs that I learned in both military and commercial aviation maintenance is to always ramp up to the desired torque setting,not down. And I agree that always setting your torque wrench to its lowest setting after use is the correct way to store the wrench after use.

Thank you for sharing. I'll store this in my memory bank.

Good video. I like this similar video also... it has a much cooler background to keep your attention!

At 1:06 he states that physics refutes the myth of the extension changing the torque...he then laughs.

Good video. I like the part where he has the 100 inches of extensions and proves it.

At 9:00 he talks about torque sticks. He says they are pretty much worthless. He also talks about when they are on a torque wrench that the torque is identical to an ordinary extension.

[QUOTE=old40ford;1905171]The wrench will click at the torque setting, but, that same torque does not transfer to the nut in question.

It appears adding extensions does not affect torque, provided you maintain 90 degrees to the work...

If you did have a loss, where would that loss go? Not really generating any heat with the torque setting found in automotive/RV applications. The extension may twist some amount under high stress, but as long as the extension did not fail, the torque applied to one end will equal the torque applied at the other.

Old 35H guy here. The inaccuracy caused by extensions, is that not all the force is twisting. Some is side force. The longer the "extension" the more twisting force is lost. Not much but some.

Most wrench specs are for +/- 4%, measured at various percentages of its full scale capability. So, a 250# wrench producing 240 to 260 lb/ft at full scale is good. We would test at various percentages of its full scale.

Never use a torque wrench to loosen a fastener.

And, yes always return the wrench back to zero when stored.

To confuse things more, when anti-seize, or other lubricants are used, the torque settings change completely.......

After a round of pop corn! My .02 cents is, it use my 30 year old Craftsman to insure a near consistency in torque on the lug nuts on both the tt and tv. Do check both while on road especially if tire has been off for bearing work or rotation on tv. Do not really care if the torque is 95 or 110 pounds as long as all the lugs are nearly the same.

Yep...which is why I don't use anti-seize.

I made the mistake of assuming that my 4 way lug wrench would work on my truck and trailer, wrong!
So I have a 1/2" tongue went just for the trailer.
