Lug Nuts - The definitive guide

wheee!

What about running aluminum lug nuts on steel studs? Another member had to drill out his aluminum lug nuts after they seized onto his steel studs... Is this common?

At least two mechanisms that can cause fasteners to seize - galvanic action between dissimilar metals and dirt on the threads. Clean the threads before installing and don't overtighten. To prevent corrosion/rust, I will sometimes put anti-seize compound (eg, Never-seez) on the threads.

How can someone make a high level chemistry comment involving Galvanic process and then make the WORST RECOMMENDATION??

DO NOT put anti-sieze on your lug nuts. Friction is a good thing sometimes. Just wire-brush the bolts before torquing down.

Anti-seize will not cause the nuts to come loose if they are torqued to the proper value. It does provide some lubrication for the threads, so, if you're real picky, you may want to adjust tightening torque. It works great at preventing rust/corrosion/galling (if you are using stainless-on-stainless fasteners, some form of anti-seize is a must to minimize galling) and makes removal much easier.

I know this is an old thread; but i've been using antiseize for over 25 years,,,originally started on heavy trucks (with Budd wheels) and carried on from there.
never had an issue with stripped or broken studs-i even use on my ~Z~
I was looking up to see what people were torquing their wheels too & 80ft.lbs. seems a bit weak.....i've been evenly torquing mine to 100ft.lbs. without any issues.

I had a Porsche that had aluminum lug nuts on steel studs and so I used a little Permatex anti-seize compound on the threads of the studs after each removal of a wheel. It's good to clean off the old anti-seize compound before putting new stuff on. Being black anodized lugs, I always used a hand torque wrench when removing or tightening nuts. The anti-seize compound is also good for the steel threads on a spark plug when it's screwed into an aluminum cylinder head.

Where you been. The anti-seize is SOP.
