Chuck is exactly right. There are dozens of Lok-tite products for many different applications/strength/temperature. I printed out the whole list from their website several years ago. The commonly found blue will probably do just fine. Start with a very small amount on clean threads. Use a bit more if the smaller amount works loose. Even the blue can be tough to get loose if you go hog wild and douse the threads, but it will also soften up with a little heat.
