    Feed blank

    Headed blanks slide down the feed rail, and the feed finger pushes each one in between the dies.

  2. 02

    Apply pressure

    The moving die slides past the fixed die and squeezes the blank between them.

  3. 03

    Form the thread

    The blank rolls as the die moves, and the thread form is pressed into its surface.

  4. 04

    Stay matched

    Both dies stay in step, so every thread starts cleanly and matches the one before it.

  5. 05

    Chipless finish

    The screw leaves fully threaded. No metal is cut away, so there are no chips and no waste.
