  • Offers lock-out position styles ideal for applications that require the plunger pin to be retracted for an extended period of time. After retracting the plunger pin, turn the knob 30 degrees, release the knob and it will stay in the retracted position via the indexing lock. In the rest position, the lock-out mechanism is completely concealed by the knob.


  • GN 822.6 mini indexing plungers feature small, compact dimensions.
  • Based on the principle of the GN 822 mini indexing plungers, this model combines their clever type of construction with a complete series of all current sizes of bolts and threads.
  • Plungers are inserted into position by holding them by the knurled knob. The wrench flats on the lock nut are exposed when the pin is retracted, so that the plunger can be easily tightened by means of an open-end wrench.
  • Steel, zinc plated with blue passivated finish threaded body.
  • Plunger pin and spring is made of stainless steel.
  • Plastic knob with black, matte finish is temperature resistant up to 230°F (110°C), not removable.
  • RoHS compliant.
