I have a Jackson DK2 Dinky Eerie Dess Swirl and needed to upgrade the locking nut.
I bought these Floyd Rose nut clamp screws, and they look very harmonious with the guitar’s purple body (the guitar has a faded color shifting from green to purple).
They might be a bit pricey for just screws, but the quality is excellent, and every time I pick up the guitar, my eyes are drawn to them. It gives me real aesthetic pleasure.
