Thread Locker recommendations.

What's the best thread locking compound that will hold well but is not permanent.

It's for the sling stud/screw that replaces the fore end screw on a Savage 99F.

Carrying the rifle slung does put some pressure on that stud, I am currently using Blue Locktite and after following mfgr instructions the set up has a tendency to loosen up.

Any suggestions would be helpful.

I would think the blue would work, but your experience demonstrates it does not. Blue is medium strength and the red Loctite 277 is hight strength. My understanding is hight heat will loosen red loctite. Is it also possible to simply replace parts in case you ever have the need to loosen the bolt? In other words cut the old bolt off and replace.

The blue should be adequate.
I can tell you what NOT TO USE. Do not use bearing and stud retainer.

I sometimes use clear nail polish, just make sure wife or girlfriend give the okay. But blue loctite is adequate and easier to remove than clear nail polish.

If blue doesn't work use red. I seriously doubt it will loosen with the red. I've honestly never had a bolt or screw completely freeze on me using red. It just takes more torque to break it loose.

I've never had blue fail on something like you are describing. Are you sure that both threads were cleaned of any oil residue before you applied the blue? If either had oil residue on them, that could easily explain the failure.

I know they offer a primer/activator which might help.

The key is clean....

Anaerobic sealants like loctite share one common theme.

The parts must be clean and free of oil or grease. Use a Q tip or similar in the threads to really get them clean.

Don't worry too much about using Red, heat is our friend.

I use a "sacrificial" screwdriver bit for screws. Choose a good fitting screwdriver and heat the screwdriver to transfer heat to the screw.

Your nose will tell you when to apply torque to the screw. Loctite has a distinctive sweet odor when it is hot enough to let go.

Beware of Locktite around plastics. It will destroy ABS.

Blast the parts clean with brakleen or kleenbore gunk out and blow dry with computer duster stuff.
I use red or blue on my harley engine parts depending on need, both can be broken loose with mild heat IF you can get a good purchase on the head of the bolt or screw.

Looks like a Harley engine would get hot enough to make both red and blue turn loose easily.

Blue or even the wife's nail polish.

Red, blue, yellow, green, the color code is a general thing. There is a whole range of products within each group. Locktite 242 (red) and 262 (red) aren't exactly the same thing.

For gun screws, I've found a product called "Guntite" works well. Applied properly (screw and hole degreased - denatured alcohol works well for this) screws stay put until you remove them, no heat required.

I would expect Guntite to hold a sling swivel stud well enough, though its not meant to be a permanent thing.

I agree. You should go to Loctite's product pages and read the descriptions of the different Loctite's. They generally include information on how much torque they will take with a standard size bolt. If cleaning doesn't do it for the product you have, look up it's torque rating and then look up the next higher one for that same bolt. Fastenal and other industrial supply vendors will carry the complete line or be able to order specific products for you.

I use red on mine, it does not loosen up and if I need to remove it I can, I love my 99 and would never do anything that would mess it up !!!!

They also make a pink for small screws like on rings and rails. The primer also significantly reduces set up time.

I use red and have taken apart and put together many things afterwards with no troubles. DO NOT USE RED ON ALUMINUM unless you don't plan to loosen again. It will strip the threads. I have never seen it damage steel. DOn't over do it. Try a dot on one side of the threads. If that doesn't work try more next time.

Use a little more blue than you have been.

I wasn't meaning I use it all the time. Moving parts most of the time. Model 94 for example.
