Does Anti-Sieze wear threads?

[nes999]

I was just using some anti-sieze on some SS bolts going into an aluminum housing and it popped a question into my head. Does anti-sieze wear threads? Like in this case I have to open it up up monthly to inspect for damage, I would assume eventually that would harm the threads.

The strange questions that pop into my head on a slow day at work sometimes scary me.

Nope. Matter of fact without it you will gall the threads with those two materials.

 

[KM223]

If anything it's designed to save threads. Especially in applications of dissimilar metals and stainless on stainless.

Like others have mentioned it will actually prevents wear especially with steel and aluminum
Just had this issue with water pump on v6 Honda previously did not use anti seize and little 6mm siezed up and broke half way out causing an extra hour to job I was doing

no , but corrosion can. PS you might consider using Loctite blue and leave it alone.

Never heard of it wearing threads. It's designed to do the opposite, save threads, prevent corrosion, prevent galling, ... There are a few different types like "regular", copper, and nickel. Use the right one for your applications (materials and heat requirement).

I use nickle for everything at work, it is what we are supplied with.

At my last job everything had to be "approved" before we used it. Some yahoo in the purchasing department bought a case of n5000 anti-sieze instead of our usual cheap stuff. Well management found out and made us dispose of it. This was the first and only time they ever let us keep anything. Normally it had to be made unuseable then thrown in the dumpster. So each one of us guys took a can home. if I use a full can if this at home I will be amazed.

Can someone enlighten me on the different uses for the different types of anti-seize? I have mostly sold the gray colored but occasionally someone wants me to order them the copper based.

Prevents rust, corrosion, & galling.

Steel bolts going into aluminum! A lot of suspension bolts!

For example, on our Jeeps the leaf spring eye bolts generally rust to the inner bushing sleeve. Even if you can rattle them loose, the rust doesn't escape very well. If you keep at it, the sleeve will come out with the bolt, and try to push through the frame bracket. So you either cut the leaf spring off, or cut the spring/shackle off, or cut the bolt off. Re-assemble with anti-seize and the problem is solved!

Regular:
A highly refined blend of aluminum, copper and graphite lubricants. Use during assembly to prevent galling, corrosion and seizing due to weathering or chemicals. Anti-Seize assures easier disassembly. Temperature range: -60°F to 1600°F (-51°C to 871°C). Salt, corrosion and moisture resistant – ideal for marine use.

Copper:
A premium quality copper anti-seize and thread lubricant that may be used to prevent seizing, corrosion and galling where high temperature conditions exist. Contains a high percentage of micro-fine copper flakes in a semi-synthetic grease carrier and is fortified with high quality rust and corrosion inhibitors. Temperature range: -30°F to 1800°F (-34°C to 982°C). Provides good electrical conductivity.

Nickel:
Protects metal parts from seizing and galling at temperatures up to 2400°F (1316°C). It is recommended where copper contamination must be avoided, under conditions of extreme pressure and temperature, and with stainless steel, titanium and nickel alloys.

-----------

That being said, I typically use Copper for my own personal use, except for stainless which I use the Nickel...

As someone else said, it protects threads and would extend the life.

Here's some reading :

The Proper Selection and Application of Anti-Seize Compounds

Here's what the Porsche workshop manuals have to say:

Optimoly HT (copper colored)
For steel - steel threaded connections and contact surfaces of assembly parts.
Never use Optimoly HT on contact surfaces of steel to light alloy, as moisture will produce corrosion.
When applied to threads, this lubricant has no effect on tightening torques.

Optimoly TA (aluminum color)
For all connections with aluminum or with magnesium, for corrosion protection.
When applied to threads, this lubricant has a slight effect on tightening torques.

I was told by a marine mechanic that it can cause wear through electrolysis.

A few too many years under the engine hatch sucking fumes maybe??

Actually can PREVENT wear by minimizing galvanic reaction.

 

[bodyguy16]

Galvanic corrosion can be avoided with dacromet coated fasteners, becoming popular in the automotive world. That's what you might want to look into.

We use the Loctite food grade stuff at work. I get so incredibly irritated when people put stainless fasteners together with no anti-seize. It causes a ton of extra work when it galls.

I like the food grade stuff because it works very well, and it washes off my hands and clothes way easier. Downside is it doesn't hold as high of temps.

 

[sberry]

I rarely use it, we simply spray most bolts with Kroil like spray, liquid wrench, just so it isn't dry when its installed. Onlyist time it really gets used here is manifolds, usually heat related stuff.

 

[mbshop]

Course it also depends on where you live. For me I rarely used antisieze. Most times it was a drop of oil and thats it.

 

[zeke01]

I just relubed a Craftsman ratchet today and used anti-sieze for the lubricant. Zeke01

I was wondering the same thing when I recently had to install stainless bolts into an aluminum engine case. I went online to order some anti seize and was surprised at how many different choices there were, regular (aluminum) base, copper, nickel, etc. I thought anti seize was anti seize. Anyway, I just ordered the regular (aluminum) based anti seize, hopeful I chose the right one.

This is what I do too.

 

[BCreekDave]

I read one time to use only the copper stuff on spark plugs as it aids the heat transfer to the head. The other mixes can be a thermal barrier.

Uh oh BCreek,

When I installed plugs in my V8, one bank I used copper....the other I used regular. It was done as a experiment to see the differences in twenty years or so when I plan to change them again.

Do any of you guys bother to go to the manufactures sites and check what their products are, the specifications, the recommended and not recommended uses are of these types of things. Instead of wandering around free parking, spend an hour on the Permatex site or the Lock-tite site. You can learn lots and not rely on the opinions of other people that are guessing at stuff.

no neat sig line

 

[FMC1959]

Not a direct answer or a written in stone fact on why to use anti seize, but I read on the vise threads, some guys that totally clean and degrease the vise will use anti seize instead of grease to lube the main screw. Enough guys do this so I guess it wouldn't wear the threads.

Reading is mentalfunda, who does that anymore? It's much simpler to google it to get the wrong answer.

Doesn't he make his living from corrosion failures?

If I had my way I'd have vehicle manufactures put anti seize on nearly every fastener they use, especially on the body and suspension.

Snapped off many a bolt and using anti seize on the others. When I removed them again years later they all came right out.

when you coat the threads the only thing is you have to watch what you torque them to. theres less friction therefore less resistance when tightening with anti seize. you don't want to over torque the bolts especially going into aluminum. check the anti seize that you have and look for what the mfg. says about torque reduction. ususally its a percentage but that changes with nickel to copper flake and also even two nickel flakes from 2 different companies may have more or less of the flake in their product.

 

[justanengineer]

Larry gives some good advice above regarding researching product specs, many of the rest OTOH are another story.

Bolted joints commonly fail when fasteners come loose or when they corrode in place. Anti-seize products exasperate the former and help prevent the later. Given that you remove these weekly I wouldnt be concerned about corrosion unless these fasteners are in a heavily corrosive environment, OTOH if your application sees a lot of vibration I would be seriously concerned about them coming loose. Depending on the product, as previously mentioned some anti-seize products can promote galvanic corrosion, commonly when folks use copper based anti-seize between steel and aluminum. Lastly, be dam careful using anti-seize products around precision surfaces, its not particularly abrasive however if you drop it down a spark plug hole or get it into a bearing you'll discover its abrasive enough.

Dear johnycomelately I pretty much said read up and ask later. I even gave some links. Read the whole thread before you give out the awards. haha now go back to sleep.

Blue locktite helps both vibration and corrosive forces. "Removing fasteners monthly for inspection of damage" I reckon this deserves some more explanation ? this will cause more wear in soft aluminum threads than anything else. Consider SS inserts yer gonna do this activity, but why.
