Plunger body: Steel, black oxide finish
Stainless steel, European Standard No. 1.4305 (American

Due to its shape, the lifting ring of GN 413 indexing plungers can be used both as a screw-in aid during assembly, or as anindexing lock (Type C / Type CK).
Versions with rest position are used in applications where the indexing pin is temporarily not allowed to protrude. After pulling out, the knob is turned by 90° to its rest position and the pin no longer protrudes. An indexing notch prevents the disengaged knob from turning back accidentally or from shock impact.
