Tension levers
Tension levers consist of a handle body and a head with either an external or internal thread, a locating hole, or an internal star profile. They are used in machine and plant construction for simple tasks requiring tensioning, especially when frequent actuation or adjustment is required. The norelem range includes various tension levers in different designs and sizes, including safety tension levers to prevent unintentional adjustments.

Tension levers from norelem
norelem offers a comprehensive range of tension levers for a wide variety of applications in machine construction and fixture technology. Tension levers and adjustable tension levers are ideal for rapid and reliable clamping, locking and adjustment operations in a wide variety of applications.
These components offer precise tension lever functions, high load capacity and secure fixation. Various designs are available, such as tension levers with internal threads, external threads, and versions with safety levers that prevent accidental adjustment.
The range is complemented by flat designs for confined installation spaces, as well as tension levers made from different materials, such as stainless steel or steel. This makes these products ideally suited for use as fixture elements, positioning elements and stop elements in modern designs.
What is a tension lever?
A tension lever, sometimes called a clamping lever is a mechanical operating element used for rapid, tool-free fixating or clamping components.
In machine construction in particular, tension levers are used as practical grips to securely clamp machine parts, stops or workpieces in place.
Tension levers function via a thread (e.g. M6, M8, M10, M12, M16) which generates the clamping force. They enable components to be positioned quickly and consistently in defined positions.
Advantages of adjustable tension levers
Tension levers are characterised by the ability to be able to secure and release machine parts quickly and repeatedly. Manual tightening and loosening is carried out quickly and efficiently without the need for additional tools.
The lever action ensures precise and secure fastening. The leverage provided by tension levers enables a high clamping force to be achieved with minimal effort.
A tension lever offers a decisive advantage in applications where operating parts need to be adjusted or replaced frequently. This is because the simple and rapid operation makes it suitable for use in frequently repeated clamping operations. Typical applications include fixture components, machine construction applications, and positioning and clamping systems.
What is the function of tension levers?
A tension lever is used to securely fixate, clamp or hold components in place on machines, fixtures or other equipment. Tension levers therefore enable rapid operation without the need for any additional tools.
The function of a tension lever is quickly explained: Rotating the lever tightens or loosens the screw connection.
Many tension levers are adjustable and have a ratchet mechanism. If the lever rotation is hindered by another component during tightening, it is simply lifted by pulling upwards. This disengages an internal toothing, permitting the tension lever to be freely rotated to a clear position and engage it again. The tension lever is ready for use again immediately, without having to loosen the screw connection.
What types of tension lever do norelem offer?
norelem offers a comprehensive range of tension levers for various clamping and switching operations. Tension levers are available with a variety of thread sizes, different forms and materials.
An overview of the key types:
Tension levers with internal threads: By tension levers with internal threads the thread is cut into the grip. It is screwed onto an existing threaded pin, bolt or screw.
Tension levers with external threads: By tension levers with external threads a threaded pin protrudes from the lever. These can be screwed directly into an existing tapped hole.
Tension levers with safety features: The safety funktion is available for both types and is designed to reliably prevent the tension lever from being accidentally adjusted or released.
Flat tension levers are particularly suitable for applications where space is limited or where a compact design is required
. In addition to tension levers, the range also includes other operating elements such as ball grips and ratchet levers.
Ball grips are ergonomic operating elements with a round grip head. They are primarily used for manual pulling, turning or switching and are easy to use without any lever action.
Ratchet levers are used to securely fixate and clamp components in place. They provide a frictional connection and are frequently used in machine and fixture construction where stable and reliable clamping is required.
What requirements do the safety tension levers meet?
Tension levers with safety functions are primarily designed to prevent machine components or fixtures from being accidentally released or adjusted. This reduces the risk of accidents and improves health and safety at work.
The key features of safety tension levers:
- Disengagement mechanism: In the rest position, the lever is disengaged from the threaded insert and, if touched accidentally, rotates freely without loosening the screw connection
- Active operation: The toothed mechanism only engages when the tension lever is pressed down or lifted, enabling the screw to be adjusted
- High process reliability: Safety tension levers ensure a constant clamping force on machines or fixtures, even with vibrations or shocks
