Abstract An extrusion head for forming insulated wire includes a fixed threaded hollow mandrel and a threaded hollow pin disposed internally of and in mating engagement with the mandrel for supporting a male die member in axial alignment with a female die member mounted within the head. The threaded portions of the mandrel and the pin are so engaged that rotation of the pin within the mandrel advances or retracts the male die member with respect to the female die member while maintaining the alignment therebetween.
