Hi all,

I have seen bolts and nuts where by either grease or copper grease has been applied to it.

I have always thought applying those is not good as it will give a wrong torque when tightening up, am i in correct?

Is lock threading grease same as copper grease?

I have seen it on number of places on both cars and bike and have always wipe it clean.

Also do think one of the advantage of applying it is , it no longer seizes and stuck to the body or in some cases weld.
What is ur view?

Thread lock is the opposite of grease

Grease stops it seizing, lock thread basically makes it seize

I've never felt the need to grease any nuts or bolts ever, only ever use copper slip when changing brake pads

Is this genuine of a troll?

Anyway...
Copper grease is applied to non temperature dependant bits. It stops the bolt seizing. Useful for stuff like brake pins and bolts that need to be removed for servicing. It does not affect torque of the bolt.

Threadlock, the clue is in the name, is to lock the thread. Useful where it's important to keep the bolt in place. Different sorts for different applications/temperature. This is where, for example, vibration may shake out a nut/bolt. Also common on engine bolts. Removal is straightforward, it's just there to hold in place, not cement it in solid.

No, he's just thick.

What is the temperature range for Coppaslip, out of interest? Always used Moly or lithium where temperature is an issue but I'm just wondering what it can't be used on.

I use Copperslip on lots of bolts
But it dose effect how tight a bolt is if you using a torque Wrench I think it 10% you reduce the setting by to get the same tension
Torque wrench measures angular tightening force not the tension in the bolt which is what matters

Nut lock stops bolts / nuts coming undone and also prevents them sizing by reducing corrosion USE NO MORE THAN MEDIUM STRENGTH often blue
High strength can make removal impossible without drilling

It does. If you look at torque specs on vehicles for things that may need to be greased/threadlocked they will give a wet and dry torque.

With a lubricated bolt it takes less torque to give the desired clamping force.

Usually like -30 to about 1000C.

I stand corrected. The figures in my head must be what I got from if copperslip applied then Embarassed

I can't say that I've ever noticed alternative torque values listed in specs.
I'd better pay more attention in future.

Only once cured. In it's applied state threadlock is a minor lubricant.

I think I worded it badly. Laughing

You will usually only have 1 value on a vehicle spec, it will have a note after it saying what sort of lubrication (if any) the fastener has, the value it lists will be with that type of lubrication.

I have seen some manuals that have a note saying all values are wet torque, then having notes on certain fasteners saying dry torque: XXX.

I can't think of a vehicle specific situation where both would be listed. I have had some instances where I have had to put both on a drawing. Usually when you have some customers which cant have any oil/thread lock near their process.
