What is a torque wrench and what is it used for?
A torque wrench is a manually operated screwdriving tool used to tighten bolts or nuts to a specified torque. A torque wrench is a manually operated hand tool designed to tighten nuts and bolts to a precisely specified tightening torque. The required torque value can be set in newton metres (Nm) before use. You can also preset the desired maximum tightening force. This is important e.g. for wheel nuts, which require a specific tightening force. It is also useful in other cases where a specific tightening force should not be exceeded. The torque wrench clicks to indicate that the desired torque has been reached.
Torque wrench sizes and areas of application
We stock torque wrenches in a range of designs and with tightening torques ranging from 5 to 800 Nm. This means our product range covers everything from bicycles to trucks.
5-25 Nm torque wrench for bicycles + motorbikes
Our 1/4-inch torque wrench is ideal for securely tightening bolts on bicycles and motorbikes. Bicycles have a smaller number of bolted joints, which are tightened to relatively low torque values. With modern, expensive carbon-fibre bikes, small torque wrenches are absolutely essential, as applying excessive torque to the carbon-fibre frame can cause irreparable damage.
Motorcycles feature a larger number of screw connections, which almost always have a specified tightening torque of between 5 and 25 Nm. As space is sometimes very limited, we also recommend our small 1/4'' torque wrench, which requires minimal handling space. If you have a 1/4" torque wrench with a range of 5-25 Nm, you are covered for almost any situation.
Torque wrenches for cars
For cars and vans, we recommend our 1/2-inch torque wrenches. These come in torque ranges of 20-120 Nm and 40-220 Nm. For passenger cars, the required tightening torques range from 40 to 150 Nm (threads between M10 × 1.25 and M14 × 1.5). Large SUVs or vans in the 3.5t range may also require up to 200 Nm. A 40-220 Nm torque wrench covers almost all applications for passenger cars.
Torque wrenches for trucks
When it comes to trucks, high to very high tightening torques are used. The tightening torque for truck wheel bolts, for example, is usually between 500 and 900 Nm, but you should always follow the vehicle owner's manual. Our 3/4-inch torque wrench, with a tightening range of 200-800 Nm, is ideal for this.

An overview of torque ranges
5-25 Nm torque wrench: This model is used for bolted joints that are not subjected to high loads. On the contrary, in some cases these are delicate applications where excessive tightening torque can damage the bolted joint or its base. Our 1/4-inch torque wrench is perfect for this torque range and also features a compact design and easy handling in tight spaces. It is ideal for use as a torque wrench for bicycles or motorbikes.
20-120 Nm torque wrench: This torque wrench is suitable for a wide range of applications requiring low to medium tightening torques. It is ideal for use in workshops for carrying out work on engines or for the maintenance and repair of small garden machinery or agricultural machinery.
40-220 Nm torque wrench: This model is ideal for car workshops and is used, for example, for work on cars and commercial vehicles. It is used when changing wheels or when carrying out work on the chassis and gearbox. This tool is also commonly used in industrial settings.
200-800 Nm torque wrench: This professional torque wrench is used when very high tightening torques are required. For example, in workshops for trucks, construction machinery, or large agricultural machinery. These very high torques are also frequently required for industrial applications.
How does a torque wrench work?
A torque wrench operates on the principle of controlled force transmission to prevent damage and material overload in bolted joints. To do this, it measures the torque acting on a bolt or nut and ensures that this torque is maintained precisely. Before use, the desired value is set on the handle of the wrench, and as soon as this torque is reached when tightening, the tool emits an audible and perceptible click.
Advantages of torque wrenches
A torque wrench offers several advantages, particularly in terms of precision and safety:
- Precisely defined tightening torques: Screws and nuts are tightened to the torque specified by the manufacturer.
- Greater safety: The precise tightening torque and optimum power transmission ensure a secure connection. This is crucial and important for safety in many applications, particularly in vehicle repair and machinery maintenance.
- Preventing damage to equipment: Torque wrenches reliably prevent screws and threads from being overtightened.
- Durability of components: The precise connection ensures that loads are distributed evenly, which protects the mechanical components and therefore extends their service life.
- Working professionally and in accordance with standards: Whenever the quality of work is a priority, a torque wrench should be used to ensure precision.
What to look out for when buying a torque wrench
When buying a torque wrench, precision, quality and the appropriate range of applications are crucial factors. Please bear the following criteria in mind:
• Torque range: Choose a wrench with a range is suitable for your application.
• Precise and accurate mechanism: A high degree of precision is the only way can you ensure accuracy in your work and maintain a high standard of quality. This is why you should look for tools that come with a calibration certificate, particularly for professional use.
• Manufacturing quality & materials: Robust materials ensure durability and reliability.
• Scale & setting: The torque scale should be easy to read and precisely adjustable.
• Ergonomics: A non-slip handle makes the torque wrench easier to use, particularly when used frequently.
Correct use of Newton-meter torque wrenches
The following should be observed when using a torque wrench:
- Adjust the torque. Select the appropriate wrench and set it exactly to the torque specified by the manufacturer.
- Select the attachment. Securely attach the appropriate socket to the wrench. When tightening the screw connection, the nut or bolt and the thread must be clean.
- Position and tighten. Seat the wrench directly on the bolt. It must be aligned parallel to the bolt plane. Now tighten the bolt slowly and evenly until the wrench clicks to indicate that the set torque has been reached.
- Remove the tool and release the tension. Once the tool clicks, do not tighten any further! This can overload the bolt. After use, set your tool to the lowest setting to extend its lifespan and maintain accuracy.
Do not use the wrench to loosen screws and remember to calibrate (adjust) it regularly.
