The clamp knob is a specialty wing nut designed to secure the base assembly on a Porter Cable router. It works in combination with the clamp screw and washer. Situations that might necessitate replacing the knob would be a broken bolt (that remains stuck inside the knob), or stripped threads within the knob itself.
