GN 5337.3 safety lobe knobs are best suited for applications where any unintended loosening of the knob may lead to accidents.
In non-operative mode, the lobe knob is not engaged with the threaded stud; i.e., the knob can be turned easily.
Only after axial pushing of the knob does the knob engage with the stud, so that it may be tightened or loosened.
After release, the serrations disengage by means of a spring.
The five lobe design is visually appealing and also gives the operator the means to achieve higher torque.
Temperature resistant to 130°C (355°F).
Resistant to solvents, oils, grease and other chemical agents.
Versions with stainless steel studs or with colored cover caps available upon request. |
