Stripped truss rod nut (Fender Am Pro)

Hello,

I recently purchased an American Professional P bass. Lovely bass and plays great, but the person I bought it from obviously used the wrong size tool on the truss rod. I can still get it to turn, but the sides are rounded down and I'd rather replace it before it gets to the point where I can't get it out. I've attached it photo, but it's hard to tell.

My question is, do I simply use the same Fender hex Allen wrench that came with the bass to turn the nut anti-clockwise until it comes off (after removing the neck first of course)? And won't unscrewing the nut add a huge amount of relief and bend the neck? If so, do I have to do it slowly with breaks or do I just go for it?

Also, is this the right nut for the American Pro basses?

Is there anything else I need to be aware of?

Thanks!

 

Great thanks!

 

Thanks for the tips!

Are you able to provide a link to the correct one? All I can find is the one I posted above. Even the Fender website only shows this: https://shop.fender.com/en-NL/parts...erican-standard-truss-rod-nut/0994943000.html

And it says "helps keep electric guitar and bass necks straight", so I assumed it's the same one for all Am Standard instruments.

I'd like to replace the nut first if possible, just to have a squeaky clean, brand new bass. But if I can't get hold of the right nut, I'll try your wrench idea.

 

Thanks!
