Knob with torque limiter CTD

threadedfinnedtechnopolymer

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 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.
