Notable Features: 
  • Very good surface finish present on the sealing surfaces. No leak paths.
  • Micro dimensions for a miniature component: (a.) Very small shaft diameter reduction at one end: .020" (.5mm) (b.) Micro diameter thru-hole (c.) Short overall length .270" (6.9mm).
  • Material waste is minimal.
  • Cold forming the pin eliminates the presence of spiral machining lines.
  • Production speeds are high allowing for low production costs. Much faster than machining.
