So I wanted to replace the plastic nut on my HB HWY-25BKS which is a beast of a machine. I learned from this experience that not all guitar nuts are made the same. The nut on the HWY is quite a bit bigger on the bottom (around 1.5mm I'd say) compared to this Graphtech one. So I had to use a bunch of wood glue at the bottom to artificially boost the height. Then comes in this nut, which fits perfectly width-wise. The only thing I haven't learned yet is if this nut is meant for a 12 inch fretboard radius like some other nuts, or not (maybe nuts don't even need to care about fretboard radius). I have mostly set up mine based on eye-feel so i dont know if this fits perfectly for a 14-inch radius originally.
