Product Description

GN5337.3 Safety Star Knob, Reinforced Plastic, Threaded Stud

These safety star knobs are designed for applications where an inadvertent loosening or adjusting of the knob may lead to accidents.

When not being used, the star knob is not linked with the threaded insert, i.e. the knob can be turned easily, but does have any effect. Only by pushing against the knob are the two serrations engaged allowing the knob to be tightened or loosened. After releasing, the two serrations are disengaged by a spring.

The five lobes provide a good grip to achieve a high torque. Reinforced for strength and long life.


Knob - Plastic, Technoplymer (Polyamide PA), glass fibre reinforced , temperature resistant up to 130°C, black, matt.

Threaded stud - Steel ST, blackened. Stainless Steel NI AISI 303

Annular gear - Zinc die casting.
