What's the right Loctite to use on scope ring screws, QD swivel mounts, general fasteners, etc? Thanks.

A torque wrench.

blue kind , medium strength

Blue is good. I'd read that red is permanent.

None of them are permanent.

Meh, 222MS.  It's purple.  This is the correct thread locker for fasteners smaller than 1/4".  Blue may work, but it may be too strong for some fasteners.

Ive seen more people tear up and destroy stuff with a torque wrench than I have with loc tite. I just tell people to use Blue and snug it down and recheck after some use.

And I've had to use a mill or a torch to take things apart more often than I like to think about.

It's a dirty job but apparently someone has to do it.

Every screw, bolt and nut has a torque spec.

Oh I agree, and most of us go just enough past it to hear that "SNAP" sound or feel the "softness" as the bolt head just shears off. . lol.

I think some of it has to do with proper use of the torque wrench, some will put it on Foot pounds instead of Inch pounds.

The newer screws (Torx and Allen) have solved part of the issue.

Torque is the still THE issue

As olekennyroy has posted, the correct answer is purple, just check the info for loctite and it gives you the diameter of the threaded fasteners for each color. That said I don't  like using loctite on guns although it may have it's place on scope mounting screws. A "smidgen" of clear nail polish on the threads will also work....<><....:)

Really?

I understand that, and even have my very own inch and foot pound torque wrenches. After puttng together a number of engines over the years, I know the importance of correct torque settings. But that wasn't my question, and it seems some people just cannot simply answer the question asked. I asked about Loctite as recommended by Pat Rogers (he didn't say which variety, or I wouldn't have asked.)

You may carry a torque wrench or two in your field kit, but I don't. However, I do carry a small multitool. That and a small tube of threadlocker might be enough for a field expedient repair.

Yep.

And you didn't  You should contact Pat and find out what he recommends.
I've never had a scope come loose in the field,  or for that matter the range, guess I'm lucky

For what ever reason, you seem to feel that you just have to have that last word. Your response had nothing to do with my question and that's it.

I didn't want to contact Pat Rogers because he appears to be a pretty busy guy, so I turned to the folks here on Arfcom who might have had some suggestions. To those that said "purple", thank you, question answered.  

Speaking of Pat Rogers, his article in the March 2008 edition of SWAT ("More Carbine Tips-Hold it, Mark it, Tighten it, Lube it") was very informative. To quote from that article, "A thread locker is not a luxury, it is a necessity."

I'm glad you have never had a scope come loose. Maybe you don't run your stuff as hard as he does.

Sounds like this thread is just about a wrap, but FWIW, Bobro recommends (and supplies the 222MS (purple) with their mounts) as well.  

Basically for scopes and mounts, a combination of correct in/lb torque with a smidge of low power loctite just as a "belt and braces" measure is the winning combo.

+1 for purple.
Scope rings are one place I always Loctite when I am sure the scope is where I want it.

Blue 242 isn't going to hurt anything, you could even go with 290, its green and wicks into threads.

I'd use Vibra Tite VC3 threadmate

I use red on scope bases and rings.
Blue on just about everything else.

If I do not plan on taking it apart red is what I use.

If you do not burn off the red before trying to take it apart, you can damage the screws.

On a somewhat related note - what is the best way to remove dried on blue loctite from a fastener?

Hold it with your pliers and heat it up with a propane torch.

How do you get the red Loctite loose on rings without damaging the scope?

I use the 222 on all the set screws on my mounts and handgun sights, and I've also used it on my RCS holsters and pouches to keep the screws in place.  Since it isn't the "strongest" one available, I can make adjustments or take stuff apart without too much effort and it still keeps in place well.

People make the mistake of using the wrong strength of thread locker more often than not. Cheapest way out...corn starch (poor mans loctite). But yes, the purple (medium strength) is recommended for low torque hardware.

I use blue mostly . My end cap for my YHM FF rail came w/ purple , which I used . If you use red , you will need a torch to remove it .

soldering iron, when i have to. I have yet a need remove a scope from a set of rings, some going on 20+ years on one rifle.
