star knob / threaded / polyamide / stainless steel
polyamide, stainless steel
Quick release star knobs GN 6336.3 are used in such applications where the knob has to be completely removed after the releasing operation and refitted rapidly for re-clamping.
The knob is tilted over the threaded spindle. When in position, the knob is brought into a straight position for meshing of the two threads on nut and spindle. The knob will then have to be turned only by fraction of a rotation to achieve clamping.
Functional safety exists only if the clamping surface lies at a right angle to the threaded bolt.
