GN 3664 Torque Limiting Three-Lobed Knobs Knob Plastic, Torque Limiting Mechanism Steel

Information

Torque limiting three-lobed knobs GN 3664 are used when the manually applied torque is to be limited.

When turned clockwise, the torque mechanical system of the knurled knob triggers an „over-engagement“ as soon as the specified torque is reached. When turning counterclockwise, the mechanical system locks such that the torque is not limited. For example, when tightening, this will ensure that the maximum permissible torque is not exceeded. On the other hand, the torque necessary for releasing will always be transferred reliably.
