    I've used fingernail polish. And I've used the loctite that's designed for threads on parts that will be disassembled at some subsequent date.

    What do you use? And, do you use it for all threaded components?

    Old model super blackhawk front sight screw gets the same locking compound as a scope mount on a gently recoiling rifle?

    Loctite Blue Threadlocker 242. That is what I use for example on scope rings and mounts.

    I only stock blue loctite - Anything I have apart is likely to come apart in the future at some point.

    Loctite Blue is your friend. Will never break in normal use, but is easy enough to break if you really need to. I've used it on everything from scope mounts to paintball air systems that operate at 1000 PSI (it's a bulletproof, no-leak solution. One hour to dry and you're set). Easier and less messy than Teflon.

    Another user of blue Loctite here. Whether for guns or other stuff, I almost always have to take it back apart.

    Although, I have used red Loctite on pins in guns before. I just prefer not to used red on screws on guns.

    I don't have a locker or safe. I keep my guns under the bed in a plastic bag.

    I use Blue, too, on most stuff-

    But for somethings, I will use RTV/Silicone Sealant/Whatever- if it's something I suspect I want to re adjust in the future, it holds well enough, breaks easy, and usually will keep the screw in the new position, at least temporarily. Also, I always seem to have some around, while the blue locktite seems to be somewhere else when I need it.

    Finger nail polish on threads with minimal vibration/stress (like grip screws). Medium strength locktite compounds on higher stressed fasteners (scope and ring screws, etc.)

    best wishes- oldandslow

    I always thought that Loctite 222 "Purple" would be appropriate for most firearms applications.

    http://tds.loctite.com/tds5/docs/222-en.pdf

    LOCTITE ® 222 is designed for the locking and sealing of threaded fasteners which require easy disassembly with standard hand tools . The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration . Particularly suitable for applications such as adjustment of set screws, small diameter or long engagement length fasteners, where easy disassembly is required without shearing the screw . The thixotropic nature of LOCTITE ® 222 reduces the migration of liquid product after application to the substrate

    Also, you can use a soldering iron to selectively and directly apply heat to small screws for removal of Loctited screws. Works marvelously.

    Blue, red and purple are the main ones and each have a specific purpose. I need to get some of the green too.

    Mostly blue but green (wicking) sure has its place too.

    I seem to be the odd man out. Red loctite is better for anything that you dont remove frequently. if you do need to remove it, use a heat gun first. Blue for things like grip screws.

    Loctite 290
    Loctite 601 [cylinders, not threads]
    Loctite 24241 [different part number for different size jug]
    Loctite 242 [the small tube]

    When i drill and tap a hole in a receiver or barrel, the Tap Magic or Moly D chemical gets in there. The screw has oil oil on it. For the Loctite to work properly, those female and male threads must be cleaned. I like to use Alcohol. Getting down into 6-48 [typical drill and tap for scope] or 2-64 or 2-56 threads I might use on a pocket knife, takes some thing like a pipe cleaner or tiny round brush.

    Red and blue Loctite. Red for scope mounts/bases. Blue for everything else I want to lock down...

    I bought a tube of Uncle Mikes Gun-tite. Its essentially blue locktite that you can pick up at any automotive store.

    I started out using clesr fingernail polish back in the dark ages. Since it did the job just fine then I'm still using it and it's still doing the job.
