Default Loose jack nut on MK guitar

Hi guys wondering if anyone knows the exact size of the nut that tightens the input jack on my Micheal Kelly, I suspect they are all universal size but I don't know that for a fact. the nut itself is not holding I think its just spinning around. Need to get a replacement. Cheers for any help

I don't know the size, but maybe StewMac can help? http://www.stewmac.com/Hardware_and_...RoCluUQAvD_BwE

I use a needle nosed plier to tighten the nut on my Telecaster where the nut loosens.

Jack nuts are not universal in size. My guess is that its likely the jack in a Michael Kelly is gonna be a foreign thread.
Are you able to replace the jack? That would be my 'knee jerk' reaction, just replace the jack with a Switchcraft jack. If you cant do that work, then its gonna be a "search and hope" operation thru a parts box, IF you have a collection of old jacks or potentiometers.

I'm guessing it is a basic panel-mount socket, in which case I would either 1)just replace the whole thing or 2) take it down to the local repairer or music store and see what they have. - They often salvage things like that from repairs.

Does the nut still grip the threads? If so, I'd just get a locking washer from the hardware store, it'll keep it tight and raise the nut up into the 'good area' of the threads (if it grips there).

Cheers guys. I would rather not replace the entire jack. The second option of suck and see seems best. I am not even sure where to start for a guess of the size ?

A little dab of "Loctite" (the BLUE Loctite, not the red Loctite) on the jack threads will keep the jack nut from loosening up, and you can remove blue Loctite with regular tools.

Also, a long nose socket on a screwdriver type handle (like a nut driver) works better than needle nose pliers to get it tight without slipping off. You can make it tight enough with one of those screwdriver handle type drivers, and not worry too much about breaking the jack.

I seriously doubt its the nut "spinning around"... its VERY likely that the threaded barrel of the nut is turning where it attaches to the body (or the fiberboard) of the jack, depending on the way the jack is constructed. If thats it, then a jack replacement is in order.

The nut itself is quite thin and flimsy. under normal circumstances your right it would unlikely be the nut. But in this case it certainly seems like it is. If I could get a match and slightly thicker I reckon it would hold. Does anyone know a ball park figure of nuts to try ? ( sizes )

Good idea Ron. I was thinking a similar idea by using a nut with greater depth
