Fits almost perfectly for harley benton HWY-25BKS
anotherharleybentonfan 08.07.2022
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.

Smooth Tuning and Reliable Performance
rewox 01.05.2026
The Graph Tech PT-6642-00 Black TUSQ XL is an excellent upgrade for any guitar nut replacement.

The self-lubricating TUSQ XL material really makes a difference in tuning stability. Once installed and properly set up, the guitar stays in tune much better, especially when using tremolo or frequent string bending. Friction points are noticeably reduced, which helps eliminate binding at the nut.

The pre-slotted design makes installation easier and saves a lot of time, especially for setups where precision is important. The fit is generally very good and only minimal adjustment is needed in most cases.

Tonally, it keeps the sound consistent and balanced, with no loss of sustain or brightness compared to traditional materials. It feels like a professional-quality upgrade that improves reliability without changing the character of the instrument.

Highly recommended for anyone looking to improve tuning stability and overall performance.

Perfect upgrade for my Harley Benton self-build single cut.
Andy Fereday 03.01.2024
I wanted to change the nut on my self-build guitar. I had ruined the one that came with the guitar by filing one slot too deep. I was worried about changing the nut as all the youtube and self-build forums advise it is a difficult task.

I actually bought two of these as I wanted a reserve in case I damaged the first installation but as it turned out, I didn't need the second. It fit the slot perfectly. Only a small amount of adjustment was needed for the string slots and it has improved the intonation immeasurably. All-in-all I'm very happy.
