ITEM NAME:5 Pieces Unbleached Curved Slotted Nut Flat Bottom For Fender 42mm x 3.5mm A9E1 5 Pieces Unbleached Curved Slotted Nut Flat Bottom For Fender 42mm x 3.5mm A9E1 Bone guitar nut for strat style neck Fits most strats with a slotted neck Nut has pre cut string slots and requires very little experience to install Size:42mm x 3.5mm x 4.5/3.5mm Quantity:5 pcs Material: cow bone String slots aren't cut real deep but cut laser perfect every time. The issue likely faced is to sand the nut to fit pocket, or pocket to fit nut, And I can both clean nut slot out, level, and set depth too. You want the cut angled uphill toward the fretboard side. I do this holding knife still, blade up, and shaving slot about 25 degree angle very little at time, then dry fit holding loose string against slot to check. Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/-1-3cm.
