oops! sorry Greg, I forgot they recycle colors a lot, I should have given the number. The 630, the second one you listed is what you want, but since you brought it up the first one is a wicking thread locker that will "soak" between already assembled nuts and bolts. While I'm shooting my mouth off, I'll also point out Temps of 500F will break locktite, if you ever need to get it apart.
