Locking bolt with lock nut

Indexing plungers GN 617.2 with plastic body are a reasonably priced indexing plunger variant. The dimensions correspond to those of the GN 617 or GN 617.1 indexing plungers. Indexing plungers Type C / CK with rest position are used for such applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° degrees after being retracted. A notch keeps the plunger in this position.
