GN 3663 Torque Limiting Knurled Knobs Aluminum, with Steel Insert

Torque limiting knurled knobs GN 3663 are used when the manually applied torque is to be limited.

When turned clockwise, the torque mechanism of the knurled knob triggers an "over-engagement" as soon as the specified torque is reached. When tightening, this ensures that the maximum permissible torque is not exceeded. When turned counter-clockwise, loosening the knob, the mechanical system is still locked so the knob can be released. Torque necessary for release will always be transmitted properly.
