False sense of security, thread locker



Original poster: "Jim Mora" <jmora@xxxxxxxxxxx>

Hello All,

Through my own stupidity I applied 710 loctite thread locker(red) to my set screws on my 12 ? rsg and twenty four hours later tried to break em loose for better adjustments. I usually use the blue on my motor cycle. Well needless to say I was twisting allen wrenches into miniature wrought iron gates.

Then I went to their web site and discovered a surprise. It liquefies at 250 C (450 F), I broke out my circuit board iron (just kidding) a Weller 140watt gun. Appling heat to the longish set screw liquefied the thread locker very well thank you.

Now this is a bit disturbing as the set screw is holding the tungsten. My experiment allowed me to twist the set screw at half that temperature although I don?t have a thermal couple.

Now the clincher. I?m only using set screws on one side of my g10 through the allthread and brass nut method the other side is securely torqued down and double so with the new red paste stick, nice stuff except for one caveavat: it liquefies at 150 C (300 F) almost lubricates?

Weren?t we just talking about flying tungsten? Would any of you material engineers out there like to offer a more suitable alternative?

Long Sparks and Secure nuts,
Jim Mora
