Has anybody ever had Red Loctite fail?
 

Has anybody have a bolt back out that has red loctite on it?


or even the Blue?

Is there anything better than the standard red?

Rob:D

only under high heat conditions

what " toolsinbox" says about heat is, for sure . correct but locktite isn't what keeps the bolt tight or in place. the preload on the fastner does. locktite is the " suspenders" in a " belts and suspenders" approach. if you have harware that repeatedly loosens up or falls out its either the wrong hardware for the application or the right hardware improperly preloaded or you have components that are moving relative to each other that the clamp load is unable to control.

+1..nicely explained - I have also seen it where the threads were over chased (both male and female) with chitty dies. I guess the fellow was trying to get locktite to work as a gap filler????

monkey spit,,,has a third product

proper prep helps too.... how you gonna glue something oily/greasey together??

+1...make sure everything is spotless...a can of brake cleaner does wonders

Might also try Green Loctite

If it has fuel running thru it and oil,so heat would not be a factor, I know about bolt stretch,but if red loctite was used how could a bolt back out?

red loctite
 

You have to remember loctite has a shelf life if it is old it does not work.Been there done that.JOHN SR
