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.

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.
An excerpt from our torque wrench assortment
Below you will find an insight into our standard range and our special production examples of torque wrenches. The complete product range as well as detailed article descriptions can be found in our catalogue.
Special Torque wrench
Since many of our industrial customers are often confronted with special bolting situations (e.g. tight spaces, enormous dimensions), we manufacture our torque spanners as special designs and according to individual customer requirements. From the special receptacle (e.g. square receptacle, spigot receptacle, special width across flats) to the special format, we will design your tool according to your ideas.

Torque wrench according to customer requirements - manufacturing examples

Special ring spanner insert
Challenge:
For a bolted joint with limited space, our customer needed a special tool to achieve a defined torque under these conditions.
Our solution:
The customer's drawing of the bolted joint (STEP file) made it clear that a standard angled ring insertion tool would not be effective at this point. Therefore, the ring was opened and upgraded with a reinforcing plate according to the required torque, which supports the thin-walled outer contour. The plate also prevents the ring from widening and slipping. After customer approval of the design drawing, the tool was produced in our manufacturing facility. The tool was then mounted in one of our presettable torque wrenches. This was set to the desired torque and sealed.
Result:
The ring insertion tool has since successfully facilitated the machining of the customer's difficult-to-access bolted joint.
+
Special torque wrench
Challenge:
Our customer was faced with the challenge of having to tighten a bolted joint to a defined torque in the tightest of spaces.
Our solution:
Looking at the customer's drawing of the bolted joint, it was clear that no simple jaw insertion tool could be used here. A standard open-end wrench was therefore designed into the CAD drawing and aligned according to the specified torque. After customer approval of the design, the insertion tool was manufactured and attached to a preset torque wrench from our production. The defined torque was then set and the components sealed.
Result:
Due to the tool, which was specially developed according to customer requirements, the customer can successfully work on the corresponding bolted joint.

Special ring spanner insert
Challenge:
Our customer needed to tighten a hard-to-reach bolted joint to an exact torque.
Our solution:
We designed a multi-bent tool in wrench size 17 to solve the accessibility problem and tighten the bolting. Repeated accuracy of the tightening torque is ensured by a 4-kt socket, allowing a CWALTER to be used.
Results:
The insertion tool has been in use for some time, making bolting operations easier for the customer
+
Special torque wrench
Challenge:
To safeguard processes, our customer must regularly carry out various bolting operations. In this case, however, the tight space conditions made the work difficult. Therefore, he needed a corresponding special tool, which also had to be limited to a predefined torque.
Our solution:
For the special tool requested, we combined a special sliding handle wrench and a torque limiter. In addition, the specified torque was set on our internal test bed.
Result:
The customer's process reliability was thus ensured by meeting all tool requirements
+
Special insert
Challenge:
Our customer in the power industry needed to tighten a locknut securing a special shaft to an exact torque. However, as the nut was recessed in a bore, tightening proved problematic due to the tight space conditions. Therefore, he asked us to design a special insert.
Our solution:
According to the dimensions, we manufactured the special insert taking into account the tight space conditions so that it could be driven with a torque wrench from our company.
Result:
The customer has been successfully using the insert to tighten the nut ever since.
+
Special hook wrench
Challenge:
A customer's custom locknut needed to be tightened to exact torque.
Our solution:
According to the diameter of the nut, we designed a hook wrench including a receptacle for a torque wrench. This was adjusted to the required torque on our test bench.
Result:
The tool now successfully ensures the exact tightening of the special nut.
Indicating torque wrenches
Indicating torque wrenches are particularly characterised by their ease of use. In order to achieve the tightening value without much effort, the current value can be easily set and read via the integrated dial with memory pointers.

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.
