What is a clamping lever?
Clamping levers are standard parts that are used in numerous industrial and craft sectors. They are part of the family of tensioning tools, which is why they are also called tension levers. Clamping levers allow for components to be securely fastened, released or readjusted with minimum effort.
A clamping lever usually consists of a lever arm, a clamping component (e.g. screw or pin) and a rotary mechanism. Their design ensures adjustability, high clamping forces and precise fastening.
A threaded insert can be used to maximise connection between clamping lever and component.
The threaded insert is particularly suitable in applications with high loads or in materials with low strength. It improves stability and durability of clamping levers.
It also ensures that they can be used reliably with different materials and applications.
How does a clamping lever work?
The basic mode of operation of clamping levers is based on a lever principle. The lever arm is moved by hand, transferring the clamping force to the component. The "clamping component" is positioned to hold the component in place.
A special feature of the clamping lever is the integrated reset mechanism. This allows for the lever to be turned back to the desired starting position without affecting clamping force. As the lever can be adjusted independently of its end position, it is easy to use in confined spaces.
Clamping levers are the perfect solution for applications that require high flexibility, easy operation and reliable fastening. Whether in mechanical engineering or assembly!

Clamping levers by norelem - our range at a glance
To meet different requirements, norelem offers a wide range of clamping levers in various designs. Whether for applications with high loads, specific material requirements or ergonomic demands. We have the right solution for every application.
Depending on the requirements, individual clamping levers are available made of the following materials:
- High-performance thermoplastic: Sturdy, lightweight and durable - a perfect choice for precise and ergonomic applications.
- Plastic: Lightweight and economical, perfect for less demanding applications.
- Polyamide: Impact and chemical resistant, suitable for demanding industrial conditions.
- Steel: Particularly resilient, perfect for applications with high mechanical requirements.
- Die-cast zinc: Durable and sturdy, with an attractive price-performance ratio.
- Stainless steel: Corrosion resistant, perfect for use in humid or aggressive environments such as the food and chemical industries.
Some stainless steel clamping levers are electrolytically polished.
Electrolytic polishing reduces surface roughness and removes microcracks. The surfaces of these clamping levers are therefore very smooth. As these are easier to clean, clamping levers are often used in food and medical technology.
Depending on the design, grip levers are available either burnished or blue passivated. The norelem range includes clamping levers in various standard sizes, ranging from M3 to M20. This variety allows for use into small, precise designs as well as large, heavy-duty machine parts.
The clamping levers are available in different colours for easy identification. Coloured styles not only make it easier to assign machine parts, but can also be used to identify safety-relevant components.
Clamping levers with internal or external threads offer similar functionalities for fastening and fixating. However, they differ in design and areas of application. Below, you can find these two versions of clamping lever. Use the filter function on the product page to filter according to your exact requirements.
Clamping levers with internal thread
Clamping levers with internal threads feature an inward facing thread. They are screwed onto an existing screw, pin or threaded rod. These clamping levers are used when a fixed connection to an existing threaded rod or component is necessary. The tension lever is often used in machines where the thread is part of the design.
Clamping levers with internal thread are not only versatile in terms of functionality, but also in design. We offer tension levers in a wide range of materials and colours.
Clamping levers with external thread
The thread on these clamping levers faces outwards. The levers are directly screwed into an internal thread of a component or a fastening element.
Clamping levers with external thread are suitable to be directly screw into an existing thread. For example, on machine tables, brackets or modules.
Tension levers with external threads are designed to fit a multitude of internal threads. This makes them particularly versatile, as they can be easily integrated into existing structures. Above all, without the need for additional adjustments. Standard parts offer a flexible solution for applications requiring direct connection to an internal thread.
Unlike clamping levers with internal threads, styles with external threads do not require additional fasteners such as screws or pins. The lever is directly screwed into the internal thread of the component, which greatly simplifies the assembly process. This not only saves time, but also reduces the number of elements required.
Easy handling and quick adjustment - advantages of clamping levers
Clamping levers offer numerous advantages that make them an essential tool in industrial and craft applications:
- Versatility: Due to the wide range of sizes, shapes and styles, handles can be customised to meet specific requirements. Therefore, they are suitable for a wide range of applications.
- Durability and sturdiness: Made of high-quality materials, clamping levers are resistant to wear and environmental influences. This makes for a long service life, even with intensive use.
- Coloured versions for better organisation: Clamping levers in different colours facilitate quick identification and organisation. Coloured grips can also be used to identify safety-relevant components.
- Quick and easy operation: Tension levers are intuitive and user-friendly. They do not require any additional tools for tightening or loosening. This enables fast and efficient handling - ideal for time-critical applications.
- High adaptability to different requirements: The clamping position plays a particularly important role, as it allows components to be fastened quickly and securely. The adjustable lever position allows the clamping position to be perfectly adapted to respective application. This ensures reliable and even power transmission.
- Strong and reliable clamping force: With high clamping force, clamping levers ensure secure fastening and stability for a wide range of applications.
