Locking bolt with lock nut GN 817.2-10-12-BK-NI stainless steel

Stainless steel indexing plungers GN 817.2 correspond to GN 817, they only differ by a longer knob. Type C / CK 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.
