  • Which grade of Locktite

    Which grade is the one that will break with a wrench. I have a zero heat application and I may need to take the bits apart.

    That is the blue colored #242. There is also a purple colored one, #222MS. It is lighter strength for small screws like circuit boards, electronics, etc. Both can be undone with wrench or screwdriver and no heat.

      Also 290, green, wicking type for assembled parts. Most often no heat required.

        Just a bit of trivia. Locktite hardens in the bolted connection and not in the tube because metal ions are the catalyst that causes it to cure.

          It does not seem trivial to me.
          I like to know how the chemical works that I am using.

            And what causes an atom in the solid metal to become ionized??? :-)

              I thought it was anaerobic, y'know like a couch tater.

                It is anaerobic, meaning that it cures in the absence of air. That is why the bottles are only half full when they are new. The air inside keeps the liquid from setting up. It does help a lot for it to be in contact with metal though. Their primer is full of copper particles that speed up the cure time.

                  I have 242 but I think I would prefer 222ms. May not be anywhere around here to get any though.

                    If buying 242 - get #243 instead. It does the same thing, but is also oil resistant, which is handy in certain applications (like small engine repair) where you can't fully degrease everything.
