Wera Click-Torque Lock C 3 is a professional torque wrench for precise tightening of screws and joints in HVAC systems, production equipment, parts assembly, and maintenance. It not only tightens to a defined torque with precision, but also loosens safely – without damaging the torque mechanism.
When working in environments where each joint has a specified tightening value, a reliable torque tool helps avoid issues – leaks, vibrations, or unnecessary repairs.
Usually, torque wrenches may be used only for tightening. For loosening you need another tool to avoid damaging the mechanism. With Click-Torque Lock C 3 that is not necessary.
Torque Lock – one wrench for two jobs
With a single slide-switch movement, the torque function can be deactivated. The mechanism is protected and the tool operates like a standard wrench.
This means:
In HVAC installation, equipment installation, and parts assembly, it is important that tightening is repeatable and meets the specification. This torque wrench is designed exactly for that.
The click and tactile feedback let you work safely even where visibility is limited or access is difficult.




Click-Torque Lock C 3 can be used in various technical tasks where controlled torque tightening is required:
The tool is built for intensive use in workshops and production environments.

Considering customers' most common tool applications, Wera has created a special kit with three sockets (17 / 19 and 21mm), a 125mm extension, and a protective cover that protects the tool from impacts and rolling. The kit is particularly suitable for car wheel changes, because with a single wrench you can both loosen the screw (in deactivated mode) and tighten with controlled torque.
