Material
Glass-fibre reinforced polyamide based (PA) technopolymer, black (C9) or orange (C2) colour, matte finish.
Torque limiting mechanism
Nickel-plated steel.
Standard executions
- CTD-B-2: nickel-plated steel boss with threaded blind hole, maximum torque 2Nm.
- CTD-B-3: nickel-plated steel boss with threaded blind hole, maximum torque 3Nm.
- CTD-p-2: nickel-plated steel threaded screw, maximum torque 2Nm.
- CTD-p-3: nickel-plated steel threaded screw, maximum torque 3Nm.
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.
