Can someone provide a link or an image for the correct blue Loctite for knife screws. The packaging all looks the same, and then there is an "automotive" 242 blue Loctite. All unnecessarily confusing to me. Like, they have to put the "blue" formula and the "red" formula in the same red tubes? Come on, guys.

Thanks.
 
Maybe this helps too ? There is a link to Loctite’s website:

 
The tube I use is part number 24200. It's 242 blue, and the tube itself is red.

I've also received white single-use tubes (no way to reseal them) with at least one knife purchase in the past, and those say they're 243 rather than 242. The blue Loctite inside seems the same to me, and I've used that as well.
 
I just go by the colour of what's in the bottle. I don't worry if it's meant for jet planes, or for lawn mowers, or for knives.
 
The Loctite 242 is what I have and use. I think the 243 I've seen said "new" on the bottle ... maybe it's a replacement for the 242?

Any "blue" Loctite should be removable.
 
related comment. i bought the original purple formula (222) and use it whenever i can (because i had paid like 15$ for it iirc and doht want to let it go to waste) but honestly it doesn't do **** :poop: for me, neither on small nor big screws/threads. really a waste of money. so weak the cured substance. seldom that i regret purchases (because i am an informed and conscious shopper) but with this product my choice was a FAIL.

i should have gone for blue formula

LOL, oh man, I feel ya.

Now which of these two would you think is red thread-locker, and which is blue thread-locker?

I think they like messing with peoples heads 😁.

On a related note, I try to avoid using thread-locker whenever possible. As long as there isn't a risk of screws falling out, or working loose pretty quickly, I like to avoid not having to use heat, or remove old thread-locker anytime I want to take a knife apart (I used to work dusty/dirty construction sites). Instead I just check the screws every once in awhile. But that's me.

Thank you, guys, I don't have to see my psychiatrist this week because you have provided evidence that I am not losing my f.-ing mind.

I was only going to use it because I thought it was the responsible knife thing to do. Nick Shabazz uses it (very modestly). I have never disassembled a knife. What do I know?

The funny thing is this: I like Nick and his videos. But the way he uses Loctite is worth-less (messing around with the knife after assembly). :) .... there really are only a few minutes and then you have to leave it alone to cure.

BTW, very useful if you work on cars or bikes as well.

I like Nick, too. He is an "aficionado." He has "aficion." Our friends in España know how important this is.

242 is correct, but even the purple 222 works great; less “permanent” than blue.
 
LOCTITE® 243™ threadlocker is an upgraded version of LOCTITE 242®, and is more of a general-purpose member of our “blue crew.” It is designed to have improved oil tolerance with surface-insensitive properties (plated fasteners no longer require primer), combined with the same overall benefits of the original Blue
 
To add to my previous post, sometimes when I want to make a screw tighter I will put a dab of thread locker on the screw, let it dry outside the knife, and then install the screw. The little bit of dried thread locker on the screw makes it thread tighter, but without adhering the screw to the pivot/post. This makes it easier to remove or adjust the screw.
