GN 7336.7 clamping knobs with indexing plunger are used for positioning, securing and clamping adjusting elements simultaneously.
The axial movement of the handle (pulling) pulls the indexing plunger from the engaged position against the spring force, with the knob meanwhile remaining connected with form-lock to the clamping screw via a hexagonal element, permitting both clamping and releasing.
Maximum heat resistance of plastic: 130°C (265°F).
