Radiused Ebony Guitar Nut – 43 × 9 × 6 mm

The 43 × 9 × 6 mm radiused ebony guitar nut is designed for luthiers and experienced users who want to save preparation time in the workshop. It provides a precise starting point without restricting final adjustment. This version has a pre-machined radius but deliberately comes without string slots. The radiused ebony guitar nut is therefore a reliable starting blank for projects requiring a nut profile matched to the fingerboard.

Ebony nuts are particularly suitable for classical guitars with nylon strings, where mechanical loads are lower and the focus is more on balance and a smooth response.

CNC-machined from selected solid ebony, the nut offers excellent consistency. CNC machining provides flat faces, a consistent radius and controlled dimensions. Its 43 × 9 × 6 mm size suits many electric and custom guitar projects requiring a thick, radiused nut. The geometry can be used for both standard and special configurations.

Several radii are available to suit the most common fingerboard curvatures. This CNC ebony guitar nut follows the fingerboard shape while leaving complete freedom to determine string spacing and slot depth. Because there are no pre-cut slots, the luthier retains full control of the final setup.

Ebony is a traditional tonewood valued in instrument making for its stability and understated appearance. A properly fitted ebony guitar nut can provide a balanced, consistent response. It also blends naturally with dark wooden fingerboards and components, both visually and functionally.

Each 43 × 9 × 6 mm radiused ebony nut is supplied unfinished. No bevels or string slots are machined. This thick guitar nut is intended to be finished with a file, cutter or grinding tool according to workshop practice. The pre-machined radius reduces initial preparation while retaining full control of the final fit.

Custom manufacturing is also possible. Special radii, adjusted dimensions and other requirements can be produced from drawings or precise measurements. This option is suitable for non-standard instruments and restoration projects.
