I measured 1.627", .119" wide, 1.4265" E to E string spacing. Machined on bottom to fit Fenders. Used on Yngwie’s Signature Stratocaster, this high-quality solid brass string nut helps open notes sound more like fretted notes. Designed for guitars with modern 9.5" radius fingerboards. Whenever you change out a string nut you should get a luthier to angle file the string slots down to the exact height required for your specific instrument, otherwise the action will be too high and the guitar will not stay in tune.
