Clamping Nut

Mechanical with integral planetary gear


  • suitable for retrofit
  • compact design allows for multiple clamping
  • intensification of clamping force possible in case of multiple clamping
  • high clamping force with low torque
  • compensates for large clamping edge tolerances
  • easy manual clamping and unclamping

Following manual positioning of the clamping nut against the clamping edge, the integral planetary gear is brought into action by turning the hexagon nut. As a result of the gear transmission, the tightening torque is multiplied. In order to reliably ensure the required clamping force, we recommend that a torque wrench is used.
