Notable Features: 
  • Very good surface finish present on the sealing surfaces. No leak paths.
  • Hole (oval) diameter is centered inside terminal flat area.

  • Flat end is trimmed perpendicular to lead axis.
Advantages: 
  • Material waste is minimal.
  • Cold forming the pin eliminates the presence of spiral machining lines.
  • Production speeds are high allowing for low production costs on high volume production runs. Much faster than machining/much less material cost than machining.
