Question says it.
The fretboard on the 90s RB250 neck in my parts banjo is perfectly flat. I want to introduce some relief to try to clear up rattle that has developed, especially on the open G and first few frets.
The one truss rod tool I have that works on the 70s neck in another banjo seems to be too big for the nut on this neck's truss rod. Doesn't feel like it grabs the nut. I know the rods are different: 70s were one-way/single action; 90s two-way/double action.
If I had nut drivers, I could just test until I found the size. But I don't.
So what size does this truss rod nut take?
Thanks.
Funny I haven't heard any rattle up to now. Don't know if it just developed. Or I'm hearing it exaggerated because I was playing with my hearing aids in. With the aids out I don't hear it as much.
If you use a nut driver I think 1/4 . Or is it for an Allen wrench ?

Nut driver on this.
1/4 is making sense. I'm pretty sure the one I have is 5/16. Seems I said that in a Hangout thread years ago. But the nut on this one being 1/16 smaller would explain why this tool isn't grabbing.
The only 1/4-inch socket I have is too small to fit in the cavity. So I just need to order an actual truss rod tool, which I'd expect to be narrow profile.
Thanks.
Best of luck .
It is indeed 1/4-inch.
All it took was a very slight counter-clockwise turn to kill the rattle. I haven't bothered to measure the relief. Using the third string as a straight edge (depressed at 1st and 17th frets) I can see there's a little clearance in the 5th to 8th fret are now, where the string was laying on all frets before. The relief is so slight I feel no difference in my fretting hand.
Don't really know where the rattle came from. I bought this neck in the fall and I think I've had it assembled in a banjo since November. It sounded great until Friday.

And where I earlier said: "The only 1/4-inch socket I have is too small to fit in the cavity" I think I meant too "big" to fit in the cavity. Its outside diameter was too fat.
