Anti-Seize and Torque

[TMS2U]

Been lookin for info on this and have not had any luck. Specifically looking at its use on lugnuts.

Does the use of antiseize affect the ability of a bolt/nut to hold a torque over time? Some places recommend that the torque be reduced by 20% if using AS

I use it on wheel studs/lug nuts at my shop all the time and have not had any problem with anything loosening up, but then again I havent taken my torque wrench to see how much it takes to break them loose after being driven for a while. They are always still tight when they come back in for their next service. You are supposed to reduce the torque to compensate for the reduced friction from using antiseize on threads. I think I will have to have an experiment with my own taco wheels, 2 with antiseize and 2 without and see if there is much difference between sides. Wonder if I can get a govt grant to help pay for the research. lol

The U.S. Navy Hardware manual recommends pre-torqueing hardware when using anti-sieze.
Pre-torqueing is achieved by torqueing the hardware to the specified torque, back off, apply anti sieze, and re-torque to specifications.
We never had a problem with holding torque on turbo shaft engine components that used anti-sieze. These engines are subject to much higher temperatures and vibrations than you'll see on your truck.
The Military's already done the research, I dont think you'll get a grant, maybe you can get a grant if you find some people willing to eat anti-sieze and prove it doesnt cause death or disease.

I've used anti-seize on my wheel studs for the entire life of this truck, and nothing's fallen off yet.

hey where you at in the navy? im at sigonella Sicily right now it kinda sucks not having my truck down here but we are getting paid pretty nice so it evens out a little bit. what kind of planes do you work on? i work on P-3s .

Retired in Sept at NAS JRB Fort Worth, TX. Wouldnt wish retirement on my worst enemy, damn it's boring.
Was deployed to Sig from Oct 01 to Apr 03 flying the Sig/Akritiri/Kuwait/Turkey/Saudi medivac/troop trans/log-run in C-40's with VR-59.
I miss the deployments, miss the Sego Pub too.
Why didnt you bring your truck? I brought my 99 over when I was stationed there from 99 to 01. Bunch of great places to wheel off base, not to far of a drive to Switzerland and Germany for some great off-roading too.
Just sold my 01 Diesel Dcab hilux w/6" lift and 33"s to a retired SCPO that lives in Lentini.

Anti-seize doesn't hold things on, that's the red and blue loctite threadlocker. Anti-seize is like a lubricant the keeps the threads from seizing together so that you can take things apart if you need to.

[DToon]

And since it acts like a lubricant, a lot less torque is required to set it to the equivalent "holding capacity". So it can be really easy to snap off a stud when the lubricating qualities allow you to turn and turn and turn when the friction does NOT develop between the threads of the nut and the stud.

But I use the anti seize and I don't use the torque wrench on my nuts!

Fortunately most of the friction on lug nuts is under the cone or under the washer. I remember talking about this in the tech section, Toyota does not recommend anti-seize on lug nuts, but I have done it for years without problems. Just be sure NOT to put it on the cone or flat surface of the washer! A few bays down from me a guy broke off a few studs on his fathers car since he lubed the bajesus out of them. Just don't use too much and may want to back off the torque a few ft lbs. Or just don't use it unless you take your wheels off often like myself.
