Hi,
I use loctite 243, blue in colour for general fasteners on the bike. It's vibration tolerant and not permanent so can be loosened with hand tools. Now I see comments for some fasteners to use Red loctite, say for the triple sprocket bolt.
My question is, which red loctite you using, there are many. I know that red is a permanent loctite, but some can still be loosened with hand tools, bot some require heat to loosen them.
Which one do you use, loctite 222, or 270 or something else.

I have red 262 or Permatex #26240 for heavy duty stuff. 270 is a bit overkill as well. In reality 243 is a good choice for the task and that's what I used. In either case thread must be clean and dry.
Red is often stated to be the choice but it's way beyond what's needed and while it can be broken free with heat, it's best left for permanent assemblies.

Thanks Ron, you have been answering all my questions.
I'm doing the triple sprocket bolt re torque at the moment and notice how old my red loctite is, expired 2012 ! Time goes fast on the shelf in the garage, but then again it's very rare I use red. Anyway, I want shopping and thought I purchased red but it's Loctite 2700, one of the newish ones. It's high strength and needs to be heated to 300c to loosen. It's green and the big thing on the tech sheets it's non harmful to us. Do you think it will be ok to use on my triple sprocket bolt or should I wait until I get some red 262.
Sorry if this is a stupid question.

That reminds me more of a retaining compound like the old 680. Without heat the damn bolt will just about snap off . 2700 requires Dismantling only possible after heating to 250°C. That's like 482F.
I got this off the spec sheet.
Something a bit tamer would be a good idea.

Hi Ron, So you used 243 on your Triple sprocket, well if it's good enough for you. I will make sure everything is clean first.
Thanks again.
Take care,
Jeff

Yes, I used 243. Not saying you can't use 262 red. I just didn't feel it needed that extreme retention. Correct torque should keep it in place and the loctite is additional insurance.

On a side note, been using harbor freight brand blue and red Loctite for years and as far as I can tell, works just as good as the brand. Looks,smells and even tastes the same (don't ask me how I know it tastes the same, lol.)

Permatex blue and red are a Loctite equivalent of 243 and 262 also. I understand the tasted thing also. Shit happens.
