Nitrided Ejector Pins
PCS Nitrided ejector pins are manufactured from precision ground hotwork steel. The ejector pins have a surface hardness of 65-74 Rc and core hardness of 40-45 Rc. Pin diameters that are 3/32” or larger are etched for easy identification. All pins are measured in inches, for JIS or DIN metric ejector pins please refer to Metric JIS or Metric DIN.
