Product Description
GN3663 Torque Limiting Knobs
Torque limiting knobs GN 3663 are used when a manually applied torque is to be limited.
When turned clockwise, the mechanical torque system of this knurled knob triggers an over-engagement as soon as the specified torque is reached. When turning anti-clockwise, the mechanical system locks so that the torque is not limited. 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 reliably transferred.
