Abstract

The stationary die of a thread rolling machine is mounted in a holder which enables the stationary die to be tilted relative to the movable die about an axis which coincides with the upper edge of the thread forming face of the stationary die. The upper edge of the die thus stays stationary when the die is tilted and remains in a fixed position relative to a track which guides fastener blanks between the dies.
