Fender's Stratocaster and Telecaster, whose specifications were changed around 1971 so that the truss rod can be adjusted from the head side.
Before that, the truss rod was adjusted from the neck end, and a nut with a cross groove carved on it (known as Phillips Head) was attached.
By turning this, the truss rod can be adjusted from the head side!
I call it Bullet Nut, but some people call it Bullet or Billet.
So I asked Google Translate to help me out, and "Bullet Nut" seems to be the closest!
By the way, why is it calledBulletis the name of the product, as you can see from the image!
It looks like a bullet, doesn't it?
And this Bullet Nut actually comes in different types!
It may be hard to tell,One is angled near the tip, and the other is angled at the tip, and the other is angled near the tip.The other has a smooth curve all the way to the tip!
By the way, there is no hexagonal or functional difference to use because of the difference here lol.
I hope this helps!
See you soon!
