Torque Knurled Handles - GN 3663

Note Torque knurled knobs GN 3663 are used when the torque that can be applied by hand needs to be limited. The torque mechanism of the knurled knob triggers a "ratchet" when turning to the right upon reaching the specified torque. When turning to the left, the mechanism locks in such a way that no torque limitation occurs. This ensures that, for example, when tightening, the maximum permissible torque is not exceeded. Conversely, the torque required for loosening is always reliably transmitted.
