Wera torque indicator with fixed torque for torx® screws'. '.strtoupper('t')amper proof'. '.strtoupper('t')he robust slip clutch guarantees a clearly audible and tactile trigger signal when the set torque value is reached, and it is therefore impossible to apply any further torque'. '.strtoupper('t')he loosening torque is significantly higher than the set tightening torque, therefore no additional tools are needed for loosening screw connections'. '.strtoupper('t')he shape of the handle fills the whole hand well and the fingers lie in the softly rounded recessed grips'. '.strtoupper('t')his ensures optimal, ergonomic power transmission.features and benefitsbull t handle is ideal for transferring controlled tightening torque and high loosening torquebull error free screwdriving due to non slip friction clutch and exact torque transmissionbull tamper proof against accidental changing of set torque valuebull particularly corrosion resistant bladecontents400 tx torque indicator, tx 25 x 5.0 nm
