The Wera Click Torque Lock C 3 is a precision adjustable torque wrench designed for controlled clockwise torque application, with a 1/2″ square drive and a measuring range of 40–200 Nm. A standout feature is the Torque Lock function, which allows the torque mechanism to be deactivated entirely, enabling the wrench to be used for loosening fasteners as well as tightening. This dual-purpose capability makes it a practical choice for mechanics, automotive technicians, and contractors who need a single tool that handles both tasks efficiently. Setting the desired torque value is straightforward and precise. Audible and tactile clicks sound as you pass through scale values, and the robust release mechanism delivers a clearly perceptible signal — both heard and felt — the moment the set torque is reached. This dual-signal confirmation reduces the risk of over-torquing, making it well suited to critical fastening applications such as wheel nuts, engine components, and structural fixings. The fine-toothed reversible ratchet features 45 teeth for smooth, controlled operation in confined spaces. Accuracy is rated at ±3% in accordance with DIN EN ISO 6789-1:2017-07, meeting the standard required for professional and calibrated torque applications.
