GN6335.9 Star Knob, Increased Clamping Force.
These star knobs have a clamping contact area which is connected to the knob via an axial ball bearing. This results in a doubled clamping force through vastly reduced friction. There is no movement on the contact area between star knob and component which greatly reduces any marking on the clamping area. In addition a reduced creep factor has been achieved by the increased preload.
Plastic, Technopolymer (Polyamide PA), shock proof, black, matt finish.
Bushes - High quality steel, nitrided, blackened.
