Torque wrenches - standard articles and custom-made products

As a manufacturer of torque wrenches, we produce according to special customer requirements. The standard range also includes torque wrenches for measuring ranges between 0.1 Nmm and 4500 Nm. Since 1919, we have been developing tools for the most difficult operating conditions and supplying them to industrial companies all over the world. The perfect tightening torque is the starting point for precision, safety and the functional efficiency (longevity) of machines and components in many industries and fields of work. The use of a torque wrench for controlled bolt tightening thus becomes a necessity and often prevents material damage. Due to the high accuracy of the torque wrenches from CARL WALTER, the tightening of screws and nuts is particularly precise and user-friendly. Based on our many years of experience, we offer our torque wrenches as standard articles or as custom-made products according to special requirements.

Catalog torque wrench

Standard torque wrench assortment for every application

The standard range is divided into mechanical and electronic torque wrenches. The mechanical torque wrenches can also be selected from triggering, indicating, presettable (with and without scale) and color-marking torque wrenches. Our mechanical and electronic torque wrenches cover measuring ranges between 0.1 Nmm and 2100 Nm. In addition, our torque wrenches can display rotation angles and store data for process standard compliance. All torque wrenches meet at least the requirements of DIN EN 6789. In addition to our standard range, we also design and manufacture special torque wrenches according to individual customer requirements.

Torque wrench - special design according to customer requirements

As a manufacturer of mechanical and electronic torque wrenches, in addition to a large standard range, we have the possibility to manufacture our tools according to the individual requirements of our customers. These special torque wrenches can be produced directly according to customer drawings as well as newly developed and designed by our experts.

Releasing type torque wrenches with scale

Releasing mechanical torque spanners ensure reliable tightening by setting the desired target value. The setting is uncomplicated via the scale with vernier on the torque wrench. Reaching the set value is signalled to the user by a loud click. Our range of triggering mechanical torque wrenches is also supplemented by the VDE torque wrenches, which are suitable for work under voltages of up to 1000 V. Due to our torque wrench production, we also have the possibility to consider individual customer wishes for the triggering torque spanners.

Preset Releasing type torque wrenches

For preset release torque wrenches, a desired torque value is permanently set on a torque tester using a setting spanner. This prevents unintentional adjustment. A clear click signal indicates that the set value has been reached. Many standard mechanical torque wrenches are no longer sufficient for special requirements. We create the right tool for every task by making the appropriate adjustments and customising them.

Marking torque wrenches

Marking torque wrenches enable visual marking of the tightened screws, as the screw is colour-marked when the set torque is reached.
The torque tightening and the colour marking are done in one operation and are therefore easy to handle.
Our colour-marking mechanical torque wrenches are suitable for a wide range of tightening requirements (male & female hexagon).

Electronic torque wrenches

Electronic torque wrenches are characterized by very high accuracy in addition to convenient operation. Through optical, haptic and acoustic signals, the electronic torque wrench indicates that the set and desired tightening value has been reached. Our electronic torque wrenches are also available with a rotation angle function. To ensure that the value is not exceeded, a warning system is activated in the caseof a torque overload. In addition, several measured values can be set and stored for different crewdriving applications and transferred to a computer. All electronic torque wrenches are also available with special plug-in parts on request.
