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

Another high quality specialized tool from STEWMAC, that makes the specialized art of Luthiery, and string nut installation, all the more easier. Another specialized tool very hard to do without...

They work great, I just feel that they are a little pricey.

Used the 1/4" nut seating file to install an LSR Roller nut in an american standard strat, the job came out so sweet it looks like it came strait from fender, the customer was blown away. Thanks Stew-Mac

These files save time and money when replacing the low end metric plastic nuts in foreign made guitars, converting to standard size nuts that are available at Stewart Mac. Thanks for providing a great selection of high quality tools and parts.

First time I felt the file is too thin, because the file is 4mm, but good size.

Delete away old glues!
Valuable tool, must have it.

Fitting a nut..Nut Seating Files

By M. Thomas Mike's Guitar Works from Manchester,TN

These files make fitting a nut a breeze. Especially, when removing old glue of the previous nut. Also,they help to prepare fretboard wood for re-glueing. IE-- they create a nice level surface.

Those are perfect to correct others' (and yours as well) mistakes. They do a neat job on cleaning caked glue on nut slots.
