Click torque wrench Wera Click-Torque C 4 Nm

The Wera Click-Torque C 4 Nm is a mechanical click torque wrench designed for precise tightening in Nm. Built in the robust Wera design and calibrated to DIN EN ISO 6789-1:2017-07 accuracy, it features a 45-tooth reversible ratchet mechanism and is intended for right-hand (clockwise) torque control. The tool measures torque up to the set value and provides a clear, repeatable release when the preset torque is reached. With a total length of 620 mm and a weight of 1.66 kg, it is suitable for professional and workshop use where reliable, repeatable torque application is required.

Advantages

The wrench offers audible and tactile click feedback when setting and reaching the target torque, a robust release mechanism that ensures a distinct release signal at the set torque, and an easy-to-set and save default torque value. Its 45-tooth reversible ratchet allows efficient operation in confined spaces and the construction conforms to the DIN EN ISO 6789-1:2017-07 standard for torque tool accuracy.

Suitable for

• Automotive assembly and maintenance tasks requiring torque control
• Mechanical and industrial assembly where Nm accuracy is specified
• Workshop use for repetitive tightening to preset torques

How to use

Set the desired torque value using the adjustment mechanism and save the default if required. Apply the wrench to the fastener and turn in the clockwise direction until the audible and tactile click is felt and heard; the robust release mechanism will give a distinct signal when the preset torque is reached. For reversal of direction, use the reversible ratchet to disengage and re-engage as needed. After use, return the setting to the lowest value for storage to preserve calibration.

Usage recommendations

Use the wrench only within its calibrated torque range and for the torque direction indicated (right-hand clockwise control). Regularly check calibration according to workshop procedures and avoid dropping the tool to maintain accuracy. Store in a protective case and return the scale to the minimum setting after use.
