Hi there.
I have a strat plus 94 with the biflex truss rod. The hole of the truss rod nut lost its grip with the allen wrench. I cannot tight it so I have to change it.
I bought a new truss rod nut.
Does anyone knows how to do it? Do I have just unscrew it out and screw the new one?
Thank you all very much.
Caipira.

Welcome.

Actually, that dark piece of walnut (wood) which the allen wrench passes through to get to the truss rod nut has to be removed first. As it is glued in, it must be heated to loosen the glue in order to remove it. Of course, where the walnut meets the maple must be scored first in order to not affect the finish. It should be noted that with these bi-flex truss rods, part of the rod's function is to butt up against the walnut plug as part of it's neck straightening function. As many do not know this, they simply drill or grind out this walnut plug and either leave it out or try to fabricate some kind of replacement concoction later as this plug is not sold separately. Guaranteed, this will look hideous and although it does allow the nut to be replaced, the rod will not be able to function normally as designed. The bottom line: Removal and replacement of this nut is best left to a competent professional.

An easier, albeit it less, "professional" way to solve your problem would be to take the next size or two larger allen wrench and taper file it to where it will firmly lock into the existing nut at some point and then securing it in even further with the tap of a hammer. This will allow the existing nut to be useful again. Granted, you'll have probably have to hammer the wrench back out too but the end result is the same.

Hi!
Thank you very, very much Martian for your time and knowledge.
I was afraid if the nut and rod would be soldered or something like that.
People like you and other good guys here makes a big difference in this world.
Thank you again. Sorry for my english.
Cheers!!!!!!
Caipira.

You're quite welcome and thank you!

There's nothing wrong with your English. Oftentimes, I feel ashamed that I cannot speak any language other than English. There are so many people, even right here on this forum for whom English is not their primary language. Yet, like yourself, they took the time and effort to learn another language (in this case, English). And again, like yourself, communicate in English quite well. My congratulations and respect to you and everyone else for this difficult accomplishment!!

Hi, me again.
Is there any other way to take the walnut out without heating it with hot water?
Is there any product available to unglue it?

Thank you again.
Caipira.

You are welcome.

You do not necessarily have to use steam (water) to remove the walnut plug. Straight heat should be able to loosen the glue joint. Granted, you want to heat the plug in such a way that it will not be scorched from the heat.

I know of no product which will unglue it. Besides, if there was one, every glued joint that this solution came in contact with would be jeopardized.

Hi Caipira, and welcome to the forum! I don't have anything to add on the issue of your truss rod. However, I want you to know that there was nothing in your writing that made me think you were not a native speaker of English. I used to teach English as a Second Language, and I can tell you that your writing is very good. So don't worry--you're among friends here!
