Locking bolt with knob

Stainless steel indexing plungers GN 613 are designed such that the plunger set in the end position (pressure spring is "on block") can also absorb axial forces. For applications in which these forces are substantially above the tensile force applied by the operator, GN 817 indexing plungers are to be preferred. The screw drivers GN 613.1 (available as accessory) shorten the assembly time and make it easier to hold the mechanism in place while fixing the lock nut. The screw driver is inserted in the side between the knob and guide, where it engages the slot in the guide.
