    Hey all! I am replacing the entire wiring harness on an old hollow body bass. The nut on the jack is stuck to it - when I turn then nut the whole jack spins with it. I have tried sticking in various screwdrivers to stop the jack from spinning but at can't seem to get a good enough hold on it with the very limited space.

    There is, of course ‍♂️, no room or washer or anything between the nut and the body. So there is no play to get under the nut, fyi.

    Any suggestions?

    Thanks!

    How about a needle nose pliers putting outward pressure on the inside out and using an open end wrench on the nut. If you had a cheap HF ones, you could grind the outside rougher. Another thought would be a bolt with threads turned sideways inside with the wrench. You are replacing the jack...so you can tear it up a bit.

    A .25 caliber bronze bristle bore brush, often used to clean 1/4" jacks, will provide some hold on the jack. I would apply a little WD-40 to the nut and let sit a few hours first.

    Could be like a last resort for you, but I'd have no problem just removing the whole thing by drilling with a small bit all around it. A plate is more professional, you can easily take it off if you need to mess with the jack.

    Sounds painful...

    Maybe try a cone shaped rubber stopper driven in, wedging in the ID?

    Or, some needle nose with shrink wrap or other rubbery grippy stuff on the closed jaws, inserted then EXPANDED to create friction on the ID?

    Or, if you are replacing the entire harness, do you have some interior access, maybe if the leads aren't final soldiered, insert the leads into a neoprene hose, and run the hose down against the inside blades/solder terminals, and it should grip pretty good to resist twisting, maybe even serrate or scallop the end of the neoprene hose to improve interference and grip?

    Gently press a tapered reamer into the jack hole and hold pressure on it while rotating the nut anti-clockwise.

    Hold the jack the best you can and try to screw the nut back on.
    Then you can clean/lube the thread before you try to get it off again.
    The part of the thread that protrudes from the nut often gets buggered and makes nut removal difficult.
    If you don't mind ruining the jack, put one jaw of side cutters in the hole and cut right through the jack and the nut.

    take a long shaft screwdriver place it into the hole this will prevent the jack from spinning, then get a 1/4 open end wrench and loosen the the nut once loose you will have to replace the the jack , use a qualityunit like a switchcraft ,cheap oriental jacks are garbage ,
    I'm a quality component snob and only use switchcraft switches and jacks , CTS pots, and orange drop caps plus quality wire like Gibson pull back wire but thats me
    good luck

    I made this for fishing female 1/4 inch jacks through hollow body guitars , saves a ton of time, its a 1/4" jack on a 24 inch rod saves massive amounts of time getting the new jack in place

    This is what I would do. Left-hand threaded screw extractor in the hole of the jack while removing the nut.

    The other clever part of the eccentric knurled tool is that it works in both directions - hold it one way to loosen the jack, hold it the other to tighten it. I also made a tool with a 1/4 male plug soldered to a piece of wire that I can use to fish the jack into position when I can't reach into the guitar itself.

    What Marty said in post#2, but insert a small bit of low grit sandpaper rolled into a tube first! Grit face to the inside of the socket of course!

    .

    +1 needle nose pliers forced open while you use a wrench on the nut.

    You can add a sandpaper strip glued back to back between the pliers and jack to increase friction.

    Likely a prior owner used 'red' locktite to ensure the nut didn't come off (and should have used 'blue' meant for future removal).
