Perhaps this should go in another section but how do you break loose blue locktite?

Quoted:
Would a small amount of heat be appropriate? regards, Ralph I've used a lot of blue loctite, and I've NEVER seen anything that couldn't be removed with the proper tool and some force. Are you sure you're dealing with blue loctite? What parts are stuck together? |

Are you sure you're dealing with blue loctite? What parts are stuck together? Yes it's blue locktite. I have one of those slip on compensators on an old barrel that I would like to take off. It has small set screws. Hard to get a purchase on them with an allen wrench. regards, Ralph |

Blue is not the super strong one, red does that job. Blue is more "medium" strength and a good choice for parts that you may need to take apart later. Red is the one that really keeps things together. It was developed for tough jobs like fixing loose bearing holes in jet engines for General Electric. (Saved them scrapping large and very expensive parts). There are other colors, some are special. Green will not set until you remove air AND then warm it up. It was developed for a special application where it was used as a seal on engine blocks. They didn't want it to harden until the engine was started and ran.
When removing parts that have had LocTite applied its a good idea to apply some heat as this really helps to make it easy to come apart. In class I use to put a nut on a 1/2 inch bolt by hand after coating it with Red LT. Let it sit for a few minutes and then let students try to take it apart cold with a normal wrench. No Go, they couldn't do it. I would then heat it up and using a rag as not to burn my hand, I would unscrew it by hand, no tools. It was a lesson on its properties. They usually remembered that one, they were dumbfounded the first time they saw just how strong the red was. |
