Mini indexing plungers GN 822.8 are distinguished for their small dimensions. They are mounted by countersunk screws. The mini indexing plungers present an affordable alternative to the GN 608 and GN 608.1 indexing plungers. In type C, the button can be turned by 30° after retracting the indexing pin, holding it in the “retraced” position using the indexing lock.
