The PRS SE Custom 24 takes a 1 11/16″ (42-43mm) PRS/Ibanez-style nut, and Graph Tech alone sells that exact shape in four distinct materials — TUSQ, TUSQ XL black and white, and the softer NuBone XB — before even counting bone and brass alternatives. These eight are real, currently-sold, correctly-shaped options spanning genuine synthetic-material tiers, an official PRS OEM bone nut, a specialist brass nut sized for this exact guitar, and raw bone blanks for hand-fitting.

The picks, in detail
Graph Tech Black TUSQ XL (PT-6643-00)
The most commonly recommended drop-in for the SE Custom 24: a pre-slotted, self-lubricating PTFE-impregnated nut cut to the exact PRS/Ibanez 43x6mm profile, though PRS SE owners report light sanding may still be needed for a perfect seat.
- 43mm x 6mm, pre-slotted PRS/Ibanez shape
- PTFE-impregnated for smoother string glide during bends/tremolo use
- Black finish matches most SE Custom 24 hardware
- Exact PRS/Ibanez nut-blank shape, no reshaping needed
- Widely reported to improve tuning stability over the stock plastic nut
- May still need minor slot/height sanding for a perfect fit
- Harder synthetic material than bone, some players prefer bone’s tonal character
Graph Tech White TUSQ XL (PQL-6643-00)
The same PRS/Ibanez-shape PTFE-impregnated nut as the Black TUSQ XL, in Graph Tech’s white finish for players who want the vintage-bone look with the self-lubricating upgrade.
- 43mm x 6mm, pre-slotted PRS/Ibanez shape
- PTFE-impregnated, same tuning-stability benefit as the black version
- White finish
- Same drop-in fitment and performance as the black version
- Better match for lighter-colored SE Custom 24 finishes
- White shows string/finger grime more visibly over time
- Same minor-fitting caveats as the black TUSQ XL
Graph Tech TUSQ (PQ-6643-00, standard)
The non-XL TUSQ nut in the same PRS/Ibanez shape — Graph Tech’s original TUSQ material without the PTFE lubrication treatment, for players who want the TUSQ tonal profile without paying for the XL upgrade.
- 43mm x 6mm, pre-slotted PRS/Ibanez shape
- Standard TUSQ composite (no PTFE impregnation)
- Bright, consistent tone versus the stock plastic nut
- Cheapest Graph Tech option in this exact shape
- Still a clear tonal/consistency upgrade over stock plastic
- No self-lubricating benefit for bends/tremolo use
- Less commonly stocked than the XL version
Graph Tech NuBone XB (LC-6643-00)
A softer, more bone-like synthetic in the same PRS/Ibanez/Jackson shape — Graph Tech markets NuBone XB as delivering TUSQ’s tonal character without TUSQ’s volume/harshness, at a lower price than the TUSQ XL line.
- 43mm x 6mm, PRS/Ibanez/Jackson pre-slotted shape
- Softer, more bone-like material than TUSQ or TUSQ XL
- White finish
- Closest synthetic alternative to a real bone tone in Graph Tech’s own lineup
- Confirmed correct fit for PRS-shape nuts specifically, not just Fender/Gibson shapes
- No PTFE self-lubrication like the TUSQ XL versions
- Less commonly stocked than the TUSQ XL black/white options
AxeMasters Slotted Gold Brass Nut for PRS SE Custom 22/24
A handmade brass nut sized specifically for the PRS SE Custom 22 and 24, from a small US maker specializing in PRS-fit nuts — brass gives a brighter, more sustained tone than either bone or TUSQ.
- Handmade, sized specifically for SE Custom 22/24
- Solid brass construction
- Slotted and ready to fit
- Explicitly listed for this exact guitar model, not a generic PRS-shape blank
- Brass tonal character is a genuine alternative to bone/TUSQ, not just a cosmetic swap
- Small-maker product, less widely stocked than Graph Tech
- Brass transmits more string ‘zing’/brightness than some players want
PRS Bone String Nut, Regular (Set of Two)
The official PRS-branded OEM bone nut, sold directly through PRS’s own accessories store in the Regular pattern that matches the SE Custom 24’s neck — the manufacturer’s own replacement part rather than a third-party interpretation of the shape.
- Genuine bone, PRS Regular pattern
- Sold as a set of two
- Sourced directly from PRS’s own accessories store
- Manufacturer-sourced part, the closest thing to a guaranteed-correct shape
- Two nuts per package covers a mistake or a future second guitar
- Sold unslotted like other bone options — still needs fitting, not a literal drop-in
- Costs more per nut than the Graph Tech synthetic options
StewMac Unbleached Bone Nut Blank
An unslotted bone blank for players or techs who’d rather hand-cut and fit a genuine bone nut to the SE Custom 24’s exact slot spacing and string height, rather than buy a pre-shaped composite.
- Unbleached genuine bone
- Unslotted — cut and shaped to fit
- Standard luthier-supply blank size, oversized for hand-fitting
- Real bone tonal character, the traditional nut material
- Cheapest raw material option if you (or your tech) are doing the cutting
- Requires nut-cutting files and skill — not a drop-in part
- No PRS-specific pre-shaping, unlike the Graph Tech or AxeMasters options
StewMac Black Bone Nut Blank
A separate, cheaper StewMac bone blank SKU in black rather than natural/unbleached bone, for a hand-cut nut that matches the SE Custom 24’s black hardware.
- Genuine bone, dyed black
- Unslotted — cut and shaped to fit
- Standard luthier-supply blank size
- Cheapest bone option in this list
- Black finish matches dark-hardware SE Custom 24 builds without needing to paint/dye a natural blank
- Same hand-fitting requirement as the unbleached blank — not a drop-in part
- Dye can wear at the string grooves over years of use, exposing lighter bone underneath
Buying tips
- Confirm your SE Custom 24 takes the standard 1 11/16″ (42.9mm) PRS/Ibanez nut width before ordering — PRS’s core (non-SE) models and the Silver Sky SE use slightly different nut profiles, and a mismatched blank won’t seat.
- A pre-slotted Graph Tech nut still often needs light sanding of the base or slight slot deepening for a perfect fit — budget for basic nut-filing tools or a tech’s time even on a ‘drop-in’ part.
- If tuning stability during bends or tremolo use is the main complaint with the stock nut, the PTFE-impregnated TUSQ XL (black or white) addresses that directly; a bone or brass swap is more about tone than slipping strings.
