I am a little curious. In the past, I have come across bolts that I take out every now and then and the heads start becoming a little damaged, or the service manual recommends replacing the bolt once removed. I bought replacement OEM bolts to replace them and they came with red thread-lock of some sort already applied. Is there a process or chemical that is required to activate the pre-applied thread-lock?

Just screw it in and torque to spec and you're good to go!

Sounds Screwed!
Spread the red juice on the threads ie screw and screw her in and wholla!
Magic stuff my friends.

The important part I remember, I made in Bold. Im not totally sure if the dry, pre-applied stuff works the same, chemically. But in application, as mentioned above; just screw em together, TQ and your good to go.

From this page: http://cjbyron.com/fasteners/loctite.html

In simple terms the threadlocker fills in the microscopic gaps between threads that exists between fasteners. These gaps allow for oxidation, movement, contamination, etc. The threadlocker fills in these gaps and turns into a type of thermoplastic that prevents movement (thereby holding the fastener from loosening) as well as prevent corrosion or oxidation too. Many of the products are anaerobic which can be beneficial (see below). There are also threadlockers that are ‘wicking type’ (220, 290, 294) so they can be applied after the fasteners are together (or torqued). See the reference page here for some links to the Loctite Company Application Guides. They will provide accurate, detailed, and up-to-date information better than anywhere else.

A quick reference to the ones that are anaerobic - what this means is that it will not set or cure until you remove it from an oxygen environment (remove it from the air) and subject it to metal ions. This is why some bolts can come pre-treated with a threadlocker or gasket sealant and still be usable. It won't cure until you thread it in and tighten it (thereby removing it from the air). It is also an important factor when deciding on using a primer.

Great information guys. Makes perfect sense now. Thanks for your help.

if it is like the OEM threadlocking agent, it never hardens. you can reuse it a few times if you take the bolt out.

I've also heard it stated, when using lock tight, use "sparingly"

"chenjinyan"...any relation to...Cha-Ching?Kinda has that ring to it!lol.
