    How to keep screws tight?

    My cartridge guide screw on my 1886 always get loose, along with the hammer pivot screw. It sometimes causes the cartridges to get stuck in the mag tube, or not even feed.
    I know people say loctite, but how tight can I put them? I know I broken a few screw heads.

    Just a drop of the stuff on the screw threads is all ya need.
    Tighten it down a bit more than finger tight/snug, you don't need to put a torque value on it more than a few inch-pounds.

    Yang down a scope mount a bit more, but that's about the only ones.

    The pivot screw's job is to stay still and not come out.
    They aren't really trying to hold things down that are under a lot of pressure like a cylinder head or something.

    Not familiar with the cartridge guide screw.
    I'd put a drop on it, and snug it down.

    There's no reason to tighten a gun screw so much its in danger of breaking.

    I have two different types of Loctite - one is stronger than the other. It works well.

    My semi-auto .22 pistol’s front sight got loose every time I shot it no matter how tight I tightened it. Finally after a range session I took it home, cleaned the front sight screw and its threaded hole with a brake cleaner type gun cleaner. One drop of blue Loctite on the screw (not in the hole), reassembled it with moderate torque and it hasn’t come loose again since 1982. It was allowed to sit and cure until the next weekend before shooting it again.

    Use the blue, if you use red you may have to put heat on the screw to loosen.

    It’s not that you tighten the screw any tighter. Just clean with some alcohol. Place a little drop on the threads and tighten as you usually would. Just snug is enough on that one.

    Use blue loctite, then you can remove the screws if you need to.

    Have a blessed day,

    If the screw is smaller than a #10 (10-32,10-24,M5x.8,etc) I start with purple loctite 222. I have had issues with blue loctite on smaller screws.

    Wrapping screw with monofilament fishing line works, too.

    tig welder will keep it from backing out. seriously though, clean the screw threads, and threads in the rcvr, and the tiniest amount of blue loctite should keep it from moving once its snugged up.

    On a lot of screws the blue locktite doesnt even need to be on the threads. If it has a head with a good shoulder. a wipe on the shoulder and mating surface and snugged down holds good. If its a fitted head in the recess its even better.

    One reason that bolts come loose is the threads are worn and mating surfaces are not making proper contact. A thread locker fills these voids hardens and adheres per the chemical composition. Select a proper product on the application with a known wway to remove the screw if necessary.

    Just use red, and if you need to remove the screws lay a soldering iron on the head til you see a little puff of smoke.

    I'm a big fan of all things loctite but sometimes they can run and cause problems with bluing etc. My brother pointed me to Vibra-tite and it's a good option.

    for sights, I find that a little dab of RTV silicone under the sight works well

    Clear finger nail polish works too. Did the scope bases on my 300 WBY 10 years ago and still tight.

    You forgot the purple font. Like all Loctite you have a choice of grades in green. 680 is the strongest and not for threads. Years ago when I was an R&D toolmaker we built a test machine. I had a couple of pivots that used 3/4 cap screw that kept on backing out. The engineer stated they would never have to be removed so I liberally applied 680. A couple of days later he changed his mind. The only way I could get them out was to heat them to a light cherry color. As soon as you lost the cherry color the screw would lockup. Loctite is a great product if you select the proper grade for the task at hand.
