    The nut on the output jack of my favorite strat comes loose all the time. Can I put some super glue or locktite, etc.. on it to get it to hold? Is there an easier solution that I am not thinking about because I, well, went to public school :)

    I'll have to order locktite if that is best. Are there different strengths?

    Don’t locktite it, use a star washer, take out the two screws, pull it apart, put in the star washer, between jack and cup, tighten well. Re-install.

    Superglue works fine, just a tiny spot is all that is needed, you don't need to drown the screw thread in it.

    Only use LocTite if the star-washer doesn't work, & definitely stay away from the RED!

    My whole state is on lockdown. Is a star washer something I can buy a single of online? I am pretty limited to amazon, etc... at this point

    Maybe nail polish? i think I remember using that on a saddle screw at some point. I'm also going a bit crazy being stuck inside, so I could be making that up

    You can, but Stew-Mac will charge you $10 for shipping!

    I've got loads of them, but I'm over 100 miles from you.

    Time to start building a parts-bin, I keep mine in one of these:

    Yup, a dab of nail polish on the threads will do it.

    I usually put the smallest drop of purple Loctite 222 I can manage on the jack threads. Nothing ever comes loose, but I can easily remove it when I need to.

    What tool are you using to tighten the nut? If you're using pliers or an adjustable open-end wrench (crescent wrench) then you're not getting the leverage you need. You need a nut driver or 1/4" drive socket and you should only tighten the nut with the jack plate removed so you can hold the jack to keep it from twisting. The right tool & technique in conjunction with the star washer is all you will ever need to keep that jack from coming loose.

    Here’s a trick I learned from BadCat. Double-nut it. Making sure that you have enough threads showing (may need to remove washers) tighten first nut, put a nut on top of the first nut, and tighten.
    It will stay put and has added benefit of stabilzing jack in the cup. (Works GREAT on amp faceplates)

    I'm using a 1/4" socket. I can't see paying a crazy shipping charge to make one appear. I'll probably try a touch of nail polish

    If I wasn't on lockdown, I'd start driving right now :) I have a bunch of spare parts, but nothing in this department. I am certain that if I get 2, one will sit here for 10 years and never be needed lol

    Looks like I might be nailpolishing it at this point.

    Search the Googlesphere for 3/8" Internal Tooth Lock Washers. The Amazonians and Ebaysters will have them and possibly your local home improvement mega-emporium. They are 3/8" steel lock washers where the ID is 3/8" and OD is 11/16". If you search for Guitar Lock Washer you will find them in small quantities for more money.

    Qstick333 -- use what you have available for now. Assume it's temporary for the time being. Just a touch of superglue or varnish (Nail Polish) would work. Not to much and don't use thin super glue. If you have a thick super glue a touch on the nut after snugging up would work. Finally never use red locktite. Blue only. Red is permanent. Blue may be to much for your application. The star washer is the correct way, but use what you have until you can get a permanent solutions.

    Why is this happening?
    Thread stripped - on either the jack, or the internal thread of the nut?
    Or,
    Is it the nut that was supplied with the jack?
    If not, maybe one is metric and the other SAE????

    So what is the correct diameter?
