Wera Click-Torque Lock C 3 torque wrench - Precise screw tightening regardless of industry-0

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.

Torque Lock – one wrench for two jobs

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:

  • No need to carry two tools
  • Faster transition from assembly to disassembly
  • Lower risk of damaging the torque mechanism
  • More convenient work on site or in production areas

Accuracy for everyday work

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.

  • Measuring range: 40–200 Nm
  • Accuracy: ±3% (DIN EN ISO 6789-1:2017-07)
  • Audible and tactile click when the set torque is reached
  • Extra click – clear and tactile fine torque setting
  • Clear main and fine scale

The click and tactile feedback let you work safely even where visibility is limited or access is difficult.

Suitable for various industries

Click-Torque Lock C 3 can be used in various technical tasks where controlled torque tightening is required:

  • HVAC system installation and maintenance
  • Installation of production equipment and regular servicing
  • Assembly of parts and mechanical subassemblies
  • Metal structure joints
  • MRO tasks in facilities with defined tightening requirements

Durable and tailored to professional environments

The tool is built for intensive use in workshops and production environments.

  • Robust Wera Impaktor design for high loads
  • Also suitable for use with electric or pneumatic tools (outside torque mode)
  • Torque Lock mode protects the torque mechanism
  • Practical textile box for easy storage and transport

One kit - wide range of applications

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.
