Well I guess my old 2006 truck had a lucky horse shoe installed when it was built, in 15 years of tires switched twice a year, all the lugs had both never seize and some white grease stuff the tire shop used on them, it only had one stud replaced in 15 years an that was due yo cross threading..
Even a lowly Grade 8.8 9/16 or 14mm wheel stud has a psi tensile strength of 120,500,you're gonna have to be using a hell'va sized impact gun.and more then a few ugga dugga's,or be a very big fella to stretch a wheel stud with a 2 ft long torque wrench,even if you use anti-seize. Tell us the last time you stretched or broke a wheel stud if you don't mind
The first sentence is correct. The second sentence is only half true, as basically there is "more to the story".
I posted a couple video's on how to do a home calibration test on your torque wrench if you're not sure how close it is Mike.They'll at least give you a rough idea on it's calibration
I worked at an automotive proving grounds for a long time and we used torque sticks regularly. We did an internal study on them and found them to be very accurate. In general I would trust a good set of torque sticks more than the $20 Harbor Freight torque wrench that a lot of people are using. We also did internal calibrations of all of our torque wrenches as it was required and very important for what we were doing.
thanks brother, I like it.
you can see each stick has a rating, just like any torque wrench once you hit that rating, it wont allow more toque, my guess it will click like a clutch. I am going downstairs to try it for first time to verify that. Gonna use a 65ft pound on my ram, my guess is it will just click.
Wrong guess. Those sticks will twist like a torsion bar when the torque us reached. There is nothing to click, they're solid metal. Take note that the higher the torque the larger each stick diameter. Impact guns aren't 100% torque, it's a hammer hitting a block of metal that tightens with each hit. Once the torque is reached the stick absorbs each impact by twisting, not allowing it to tighten any further.

That makes sense. Thanks for taking the time to explain it!Wrong guess. Those sticks will twist like a torsion bar when the torque us reached. There is nothing to click, they're solid metal. Take note that the higher the torque the larger each stick diameter. Impact guns aren't 100% torque, it's a hammer hitting a block of metal that tightens with each hit. Once the torque is reached the stick absorbs each impact by twisting, not allowing it to tighten ant further.
So is you won't hear a click when tightening, if you DO, that's the sound of your lug breaking.
I said that in a previous post. today impact guns can easily provide over 1000 ft lbs. there are many impacts out there that are only 250 ft lbs. Before I bought my torque sticks I did some research and found multiple people saying they had to reduce power to their impact by reducing airflow for pneumatics or switch to lower on electrics to get consistent accuracy with their sticks. I didn't try various guns myself, just the one I use so are those people correct, can't say for sure but they make a good case. as you pointed out, if you sit there and let your impact whale away on that nut after it seems to have stopped turning you WILL get higher torque than the stick is rated for. I did try that when I first got my sticks. That's where common sense comes in. So when tightening, stop when the socket stops turning. a good idea is to put lines on your lug sockets so you can see that it's not tightening and you know to stop there
Correct. The torsion bar affect absorbs the impact and doesn't let it tighten anymore. For anybody with experience using impact wrenches you know that regular extensions and swivels greatly reduce the power of an impact because they are absorbing some of each hit of the gun. Impacts also are not very effective for trying to loosen something like a bolt in a rubber bushing (like a leaf spring bolt) because the rubber/bushing is absorbing the impact. Kinda' the same philosphy as to why torque sticks work.Wrong guess. Those sticks will twist like a torsion bar when the torque us reached. There is nothing to click, they're solid metal.

I found the same when I had to remove some Tapcon concrete screws in concrete (1/4" x 5" long with threads only on the lower 3rd of the screw). My impact driver (Ridgid octane with 2400 in lbs torque = 200 ft. lbs.) couldn't loosen them because of the torsion effect. grabbed a ratchet and the screws came out with minor effort.
