Graph Tech PT-6143-00 Black TUSQ XL 43 × 6 mm Slotted Guitar Nut

Best for

Replacing or upgrading a dimensionally compatible right-handed six-string guitar nut when a black, pre-slotted, lubricated Graph Tech material is preferred.

Who should skip

Skip it if the guitar needs a different length, 6 mm thickness, height, R-20 radius, 35 mm spacing, left-handed slot pattern, white material, unslotted blank, or guaranteed no-fit-work installation.

Watchouts

PT-6143-00 is the black right-handed variant. Do not confuse it with white PQL-6143-00 or left-handed 6143-L0 variants. Brand/model associations are not a drop-in guarantee. The current image has six visible slots; the prior five-slot alt was incorrect.

Likely add-ons

• measurement tools for confirming the existing nut and slot
• appropriate files and abrasives or a qualified guitar technician
• installation adhesive only as appropriate for the instrument and repair method

Verify before buying

• Does the existing nut measure approximately 43.0 × 6.0 × 8.88 mm?
• Does 35.0 mm string spacing and R-20 radius match the instrument?
• Is a right-handed black six-string pre-slotted nut required?
• Can the installer perform final sanding and string-slot setup?
• Is PT-6143-00 required rather than PQL-6143-00 or a 6143-L0 left-handed variant?
