Good writeup for reference.

Interesting read

Good article, I have built a few motors in my day and must say I
have used very little anti -sieze. I know some guys use
it to coat exhaust header bolts,where else is it used in auto repair
and auto rebuilding? tks ed

The other place that I can think of is when you use fasteners into a dis-similar metal, like a steel bolt into an aluminum head. But it is not limited to this. Should also be used with stainless hardware to prevent galling

One of the best places I use it is on wheel studs....as long as you torque the lugs correctly you won't have issues with them coming off and when they do have to be removed it's much easier.

I'd be careful with that one, as the stock torque specs are for a dry bolt/lugnut and you're adding lube into the mix. It'll require less torque to reach the same clamping force as the stock/dry approach, but figuring out the correct torque with lube is outside my pay grade.

Going to stock torque values with lube would probably result in stretched/weakened studs.

As a counterpoint, there are a ton of people who do not install lug nuts with a torque wrench. Maybe even majority of people. That is probably a bigger no-no than using anti-seize.
