stripped truss rod nut

[therex]

OK. Just to revive this thread.

I have a similar problem to the above. The Allen-Key socket is stripped out & I can't adjust the truss rod.

Now this ain't an expensive bass - it's a neck-thru' Hondo/Satellite/Aria - definitely a Matsumoku build - and therein lies the problem - it's neck-thru and the adjustment is via a deep groove in the body at the neck/heel end.

I can only get the right-angle of an Allen key (5mm) in and that *just doesn't* catch, so I can neither tighten nor loosen.

I've read about the extractor (above) but I don't think it'll get into the nut due to the angle.

My next nearest/bigger key is a 5/16 and this won't fit, even with a helping bang from a hammer.

Has anyone got any tricks/advice for this one?

Does anyone know if all truss-rod nuts that take a 5mm key are the same size fit on the rod?

Thanks for any advice.

you could make the key to fit, not sure how though, but the lutheir who repaired mine molded a new key and that way he taked out the truss rod nut and put a new one in there

Were can I find a replacement nut? I found a Fender bullet style online, and a Fender x type, but the nut on my bass is cylinder shaped (allen) at the bottom of the neck (dual action truss).

so, using a screw extractor to remove the stripped nut and then replacing it is the best choice?

are all truss rods uniform size? how would i determine the thread diameter?

where is the best place to buy a new truss rod nut?

I used this tool from stewmac to remove the stripped nut on a cheep 80's P bass. It works very well. Invalid Link Removed

Bevel the edges of the 5/16 size with a file until it fits in there. Take the nut out, and get a new one.
