Replacing Truss Rod Nut on SR885

[improvpwnd]

Hey guys,
I am replacing my Ibanez SR885's truss rod nut because it is close to being completely stripped. I have had the bass a long time--through the period when I didn't know anything about setup, but experimented anyway. So, I pulled it off, it looks "standard"...I searched Stewart Macdonald and found the Fender X-style Truss Rod Nut (offered in 8-32 or 10-32 thread) and a Bullet Style Truss Rod Nut (only offered in 10-32 threat). I like the idea of putting an X-style nut in there so I can use a screw driver to adjust, but will this nut fit? What is the difference between 8-32 and 10-32 thread and how can I tell which one I have?

That's the difference in the diameter of the rod it fits, and the number of threads per inch.

Take the old nut to your hardware store, find the 8-32 and 10-32 bolts, and see which one the nut screws onto and fits well. There you have it!

OK, but does that mean that a Fender 8-32, for instance, will fit my Ibanez 8-32? In other words, is the thread size the only specification I should be concerned with?

I've got a question relating to this.
The trussrod nut on my Proto J is a little off center and it does not turn very easily.I was thinking I might put in a nylon washer to ease the friction and bring the nut forward a little to be able to reach it better with the wrench.I'm just afraid that once I remove the nut I might not be able to get it back on.I've neverr done that to a bass so I'm worried.Can trussrod nuts be removed without risk of anything falling apart inside the neck?

The first number refers to the nominal diameter of the screw. The second number is the number of threads per inch. An 8-32 screw has a nominal diameter of .1640" and 32 threads per inch. A 10-32 screw has a nominal diameter of .190" and 32 threads per inch. Obviously the nuts are not interchangeable. Whenever threading a nut onto a truss rod it is best to turn it left until it clicks or bumps. When it does that the beginning threads of the nut are lined up with the beginning of the threads on the rod. Turn the nut to tighten. If you do that you should never have a problem with cross threading.

BTW, 8-32 is 8-32. It is an engineering spec and an industry standard. Brand names do not matter.

OK, so I took the nut into a hardware store and when fitting it on the thread size measurement palette, I found that it best fit a size called "M6-1.0" It did not fit on the 8-32 or 10-32 thread sizes--my nut was too big. If the first number is diameter of and the second is threads per inch, what the heck does M6-1.0 mean?

Be careful, you may need a replacement nut as well if you have stripped the threads on the nut itself. If you stripped the truss rod threads, your gonna need a whole new rod which is a much bigger problem.

M= metric
6= major diameter
1.00=thread pitch

Take your guitar to the hardware store and find the proper nut for the truss rod.
