General information

Features and applications

CTD wing knobs are used when the applied tightening torque must not exceed a preset value.
The torque transmission from the wing knob to the clamping element takes place by means of a spring-based mechanical system which prevents the overcoming of the established torque. Upon exceeding the established torque, a "click" sound will be heard to indicate that the maximum tightening has been reached. By turning the knob anticlockwise the mechanism unlocks.
