Nut Seating Files

About This Item

Sturdy files for cleaning and squaring nut mounting surfaces. They file only the bottom of the slot, leaving the side walls unscarred.

These files have fine and medium cutting surfaces.

Each file is 7-3/8" (187.33mm) long, with 4" (101.60mm) cutting surfaces and a rubber-coated handle. To keep the file from binding in the slot, we have designed these files to be slightly narrower than the nut size specified. An undersized file also helps to prevent widening the slot width—ensuring a snug fit for your nut.

5055 For 1/8" (3.18mm) wide nut Works for Fender® guitars and basses
5056 For 3/16" (4.76mm) wide nut Works for Gibson® guitars, basses, banjos, and mandolins
5057 For 1/4" (6.35mm) wide nut Works for classical and Dobro® guitars

Nice file

(Customer's Reviews)

Good quality file with comfortable grip, a specific file for a specific job, nice precision quality item.


excellent tool

(Customer's Reviews)

I'm building my first fender style instrument (a precision bass) and needed this file to insure the base of the nut slot is flat. Works fine.


Too narrow

(Customer's Reviews)

I got the 1/8" file to level Fender nut slots and its much too narrow. You have to move the file from side-to-side and at an angle across the slot to get a level slot. I could understand making it slightly undersized so it doesn't bind, but its too undersized.
