With a holder for insert tools for controlled right and left tightening. Triggering for work in mass production. The adjustment knob can be unscrewed after setting the release torque to prevent unintentional changes to the target torque. The included locking screw further protects against tampering, as do the accompanying adhesive seals. No adjustment is possible without seal breakage. QuickRelease safety lock for fast, precise adjustment through QuickSelect quick adjustment. Double stop signal and very readable double scale with color differentiation of N.m/ft·lb and ft·lb/in·lb. Left tightening by reversing the insert tools. 2-component handle, resistant to oils, fats, fuels, brake fluids, and Skydrol. Accuracy ± 3% tolerance from the set value. Special feature: no reset to "0" required, as the measuring element is only loaded during the tightening process. Further loading after triggering or loads against the functional direction, e.g., with stuck screws, do not affect the release mechanism, thus protecting it from damage. Additional technical features: Certificate: yes, inspection required: yes. Includes calibration certificate according to DIN EN ISO 6789-2:2017 and operating instructions. Delivered in a plastic case.
