Does Anti-Seize Compound Work?
 

Project Farm youtube channel has some cool tests they do. This time its all about how well anti-seize works on bolts as well as corrosion resistance. He even accounts for rust and heat in his testing.

They compared:

Loctite Copper
Permatex Aluminum
Nickel-Graf
Lubri-Matic High temp grease
Fluid Film
Candlewax

Just don't use it as a motor oil... (duh). :D

I just watched this last night (and fell asleep before it got very far). Such a coincidence (or maybe not).

So, ...Permatex or Loctite (especially Loctite).

Yeah I antiseize or grease everything I put back together.
I have always used copper and high temp grease.

I think I used a little engine oil on the head bolts when I did my head gasket... I hope that works. But I think I snapped on of the mounting bolts on the starter because I did not use antiseize (or anything) when I swapped my transmission.

We experimented at Huge aircrash back in that '70s with torque to pressure and got not repeatable results until the bolts were lubed. Anti sieze wasn't common except for copper sulfate, but most either prevented dissimilar corrosion fretting or provided a lube effect.

My suspicion is your bolt was over torqued and it's head failed after granular corrosion.

Ditto. Its so nice going back and not having to fight with rust.

Wouldn't antiseize risk a torqued bolt or nut backing out over time? That is the reason I don't use it unless specifically recommended. Not true, I guess, huh? You can apply it everywhere?

yes. If vibration or other cycling forces are going to loosen the bolt, the anti sieze won't change that.

As long as you torque any bolt properly it will never back out. That being said, I always just hand tighten almost everything. Head bolts and bearing caps are the few exceptions. With both of those taken into account, I've used anti-seize for years and never had an issue of bolts backing out.

I use that stuff on just about everything once I realized there appears to be no difference in the bolts backing off.
When my friend got his Toyota pickup it was 10 years old. It needed some suspension work. Stuff had to be taken apart with a torch or sawsall. 12 years later he is having to redo some of that suspension work again as its wearing out again. Everything that was antiseized just came apart.
