General information

Features and applications

VTD knob is used when the applied tightening torque must not exceed a certain value.
The transmission of the torque from the knob to the clamping element takes place by means of a spring system which, upon reaching the required torque, releases the knob. When the established torque is exceeded, a "click" will be heard to indicate that maximum tightening has been achieved.
By turning the knob anticlockwise the mechanism (Elesa patent) unlocks.
The knob has been tested up to 60000 tightening cycles and the values of the torque were unchanged.

Other executions

Special executions on request

  • Knobs with threaded screw.
  • Knobs with different values of max. torque.
  • Knobs with stainless steel metal parts and NBR synthetic rubber O-Ring.
  • Knobs with cap supplied in other colours.
