The evils of threadlocker

From Henkels website:

Use 222 Purple for up to 1/4" - This is us, people, but you should not need it.
Use 243 Blue for 1/4 to 3/4" - Don't, just don't.
Use 277 Red for OVER 3/4" - If I catch you, I will beat you with a 2x4.

Rant on:
WHY IN THE *^&%# WOULD ANYONE PUT THAT EVIL RED CRAP ON A FIREARM????? If you think you need it, then maybe try fixing the underlying problem instead, FFS.

It should hold on it's own. Even using Purple is a crutch.

Also consider that wet threadlocker is a lubricant and when using it, you must reduce your dry torque specs by 15-30%. So 35 in-lbs max on a wood stock becomes 28 in-lbs if you smeared idiot juice all over the screw. So BUY A &@%$)(& TORQUE WRENCH!

Do you know that the barrel threads are RIGHT THERE? You better not have squeezed any of that garbage into them...
Rant off:

Thank you for listening. I feel better now.

What about orange ?

I got some of the promising do-all orange and promptly mislaid it but if I find it I'll let you know, lol. Loctite is essential in fixing scope mounts in place, IMO, at least the older ones. One bad experience converted me forever. On screws of that size, I've never had a problem with the blue stuff, when I couldn't get the purple. It can be very hard to find in stores, even in the good ones that carry a lot of loctite products it seems that most users want the thermally resistant red versions, which would not be for firearms purposes.
 
I only have blue and red. The red is probably 40 years old and was my fathers - it never gets used.

I use blue on anything and everything that needs help - I didn't realize that was a problem.

Case in point - I bought one of those TC-73 rifles. The thing was disassembling itself regularly within 150 rounds. Over the space of a couple range sessions I ended up putting blue threadlocker on EVERY metal to metal screw, and I do mean every one, because no amount of torque was keeping them in.

Yes, I believe that the build quality on those things isn't great if it shoots itself loose unless you gum up the threads with that gunk. I'm surprised that the wood screw in the stock wasn't creeping out lol

Scope rings and bases don't really need them. I've never shot a properly torqued optic loose.
 
Definitely don’t use the green stuff that says it’s a sleeve retaining compound unless your absolutely sure your never ever going to take it apart!
I’ve said many swear words trying to take some rc cars apart to repair
Manufacturers must have a red loctite monkey in the factory with a 45 gallon drum of the stuff…
 
All right you guys, now that I've calmed down, some of you have a point. Also, not many people are aware that there is an option a little milder than Blue.

Mark - II: To be fair, I might have done the same thing here. The underlying problem of poor build quality is not repairable so you're not left with much choice.

270WSMXBolt: Sleeve retainer, really? Yuck. And what implication?

Big Bad: I have to say I disagree with you here. I have dealt with poorly fitting scope mounts. It happens on new rifles too, BTW. In one case, it was a design flaw on the action that required switching to a different mounting solution. The second one required bedding the bases. I have not dealt with many older rifles, maybe my opinion would change then, especially if threads were getting worn out.

FLHTCUI: On a hunt of a lifetime, would you take a new rifle, with it's unknown issues or would you take old faithful?

To all: I stand by my original statement that Red Locktite is Evil and I will still hit you with a 2x4.
 
I have access to partial bottles of nail polish that are stored in the fridge. Get to pick whatever colour I want when I can’t find my blue thread locker. About on par with nail polish when it comes to disassembly. Have a small heat gun just in case but have only used it on stuff that was glued together by other ‘gunsmiths’.

I work in heavy industry. That green locktite will take approximately 80 tons of force when set. We had a crane wheel we had only .002” fit on (20 tons of force approximately in the press, for the size of bore should have been .006-.008” fit) and it had green put on to make up for lack of fit. Took over 100 tons of force to disassemble later on.

Important to use the right product at the right time.
 
Everything has a place; use to much or the wrong one and pay the price.
Very frustrating when someone else used the wrong product and you get to suffer through it…
I’m not the biggest fan of 262 but when I built engines select internal fasteners would get a drop (think rod bolts).
But I’m a total fanboy of 243 on stainless steel.
I swapped to stainless fasteners on my Harley and used 243; no galling and nothing has ever come loose yet it’s easy enough to take apart.
I use it on scope mounts as well and I have not had an issue to date but you do have to chase the threads if you take it apart and expect to reassemble it.
