The external diameter of the ferrule is 6.5mm.

The diameter of the flange on top of the ferrule is 8mm.

The internal diameter of the hole at the top for inserting the string and nut is 6mm.

The internal diameter of the hole at the botton ( through which the string must pass but not the nut is 2mm.
