VTD Torque limiting knob in technopolymer |
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. |
