Specification
Information

Threaded body: Steel, black oxide finish  
Plunger pin: Stainless steel, European Standard No. 1.4305 (American Standard Series 303)
Knob: Matte black technopolymer plastic (Polyamide PA)
Lock nut: Steel, black oxide finish, ISO 8675
Countersunk screw: Stainless steel, European Standard No. 1.4301 (American Standard Series 304), DIN 7991


GN 817.8 indexing plungers have been designed so that special versions of the indexing pins can be made economically in smaller unit quantities.
If required, the indexing pins can be machined or made by the user as shown in the drawing above. They are assembled with a countersunk screw and can therefore be assembled several times. All parts are supplied individually as a disassembled set.
Type C / CK indexing plungers are used for 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.
Maximum heat resistance of nylon plastic hand knob: 110°C (230°F).
