……………………………………………………………………………………

Please note: pre-shaped nuts are not generally drop in replacements. Some sanding or shimming may be necessary for proper fit. To shorten the height or width of the nut, you can place a piece of sand paper on a flat surface. Carefully and evenly move the nut back and forth with equal pressure to desired thickness or height. Depending on your string size and fretboard radius, some slot filing may be required as well.

Do I need a flat bottom or curved bottom nut?
  • Most, if not all Fender Squire, and other Strat and Tele style guitars made oversees (China, Indonesia, etc.) use flat bottom nuts.
  • In most cases, Fender’s made in the US and Mexico use curved bottom nuts ranging from 7.25” to 12” radius, with 9.5” radius being very popular found on many American and MIM standards.
  • This nut cannot be used as a replacement for a curved bottom nut.

Do I need 42mm or 43mm?

That could depend on your guitar or your preference. Many prefer a 43mm nut over 42 regardless, because 43mm sometimes gives slightly wider string spacing, and/or the opportunity to sand the ends of the nut to precise width of the neck…or not. For an exact replacement, it’s best to measure your present nut or go with what is spec’d by your guitar manufacturer (see Fender website for example). Many Fender, Squire, and other Fender style guitars specify 42mm nut. Some spec 43mm or (42.8). The difference between 42mm and 43mm is very slight (42mm is approximately 1.65” or 1 5/8”— 43mm is approximately 1.69” or 1 11/16”). Important to keep in mind too, that sometimes manufacture specifications can differ slightly from what is actually on the guitar.
