So, those wanting to replace the NUT on the Player Stratocaster, you need to know the various measurements in order to order the correct NUT. Well, here you go! The Nut has a curved base, that is, it matches the fretboard radius. It is NOT FLAT on the bottom edge. NUT SPECS Length 42mm Thickness 3.1mm Height 4.3mm SLOT SPECS Max Depth 2.15mm at Centre Depth at Low E 2.15mm Depth at Hi E 1.9mm Width 42mm HOW REMOVE NUT? Removal is a matter of running a sharp blade along both front/back edges, then use a small wood block and hammer, gently tap the nut ONLY sideways. Very minimal force directly on the nut, not any portion of the neck is all is needed to shift the nut. Tap away to at least halfway out before lifting the nut out. Presto! See the NUT base matches the neck radius.
