  • GN 717 indexing plungers are characterized by small dimensions.
  • Universally suitable due to their prevention of misalignments and positioning errors of mating indexing bores.
  • Lock-out types are used for applications where the plunger pin needs to stay in its retracted position. To achieve this, the knob is rotated by 90° after being retracted. A notch keeps the plunger in the retracted position.
  • During assembly, the maximum tightening torques should not be exceeded when securing the lock nut.


  • Stainless steel threaded body or steel threaded body, zinc plated with a blue passivated finish.
  • Plunger pin and spring is stainless steel.
  • Plastic knob with black, matte finish is temperature resistant up to 230°F (110°C), not removable.
  • RoHS compliant.
