Increased hold and stability with grips from norelem
Grips are standard parts that are used in numerous sectors. They serve as functional elements that enable safe and comfortable operation. In addition, grips contribute to the ergonomics and aesthetic appearance of a product.
Different grip types fulfil specific requirements for hold, stability and handling. They are designed to be optimally suited for the respective area of application. The grip variants from norelem are characterised by their high quality and carefully considered design. Palm grips and star grips can be mounted onto threaded spindles.
Whether being used in demanding industrial environments or for operating machines, the correct grips not only provide a better hold, but also improve the safety and efficiency of the application.
Other operating grips, clamping levers and similar control elements can be found in the 06000 product category. We provide you with the CAD data free of charge so that you can get a feel for the individual products. Use the link to find out how you can download it directly.
What are palm grips?
Palm grips are control elements that are used mainly in machine construction. The grips consist of a central grip body with opposing grip arms arranged in an X shape. The grip enables a good transfer of force by applying the force from all sides.
Some grips are drilled through so that they can be fitted onto a threaded rod. Others have an internal thread. The grips are also available with external threads as part of the grip or pressed in.
Palm grips are available in materials such as plastic, thermoset, aluminium, stainless steel and grey cast iron. The body size, height, thread size and length can be freely selected using the filter function.
The symmetrical arrangement provides an ergonomic means of applying a significant amount of force. These grips enable even force distribution and facilitate the tightening or loosening of screws that require high torques. They are used in particular where operators have to repeatedly loosen or tighten connections, but at the same time, also require a stable and controlled grip.
In machine tools and production plants, these grips are often used to adjust clamping fixtures, screw connections or to operate tools. In system and apparatus constructions, they are used to operate components that require a high torque. These can be large valves or clamping mechanisms. In workshops and for assembly work, palm grips aid the tightening or loosening of screw and clamping elements.
Some grips are manufactured according to DIN 6335 standards or are based on it. DIN 6335 is a standard that covers palm grips. DIN 6335 specifies the following to ensure safe and efficient use in a range of technical applications:
- how palm grips should be designed and dimensioned
- what material they should be made from
Our customers' favourite versions:
- Palm grips similar to DIN 6335
- Grey cast iron DIN 6335 palm grips
- Stainless steel palm grips similar to DIN 6335
- Aluminium palm grips similar to DIN 6335
Advantages of palm grips and star grips in comparison
The choice between a palm grip and a star grip often depends on the respective application and the specific requirements. Both grips offer ergonomic solutions for manually transmitting torque, but they differ in terms of handling and application. We have compared both grip types for you.
A palm grip enables better leverage, as the force can be applied symmetrically. This is particularly advantageous when high torques are required. The size and shape determines the amount of force that can be exerted. They ensure a more stable and strong rotation which makes these grips ideal for applications where a lot of force is required.
In addition, palm grips are particularly suitable for applications where less precision is required. The shape ensures that the grip position is always clear and symmetrical, making it easier to turn.
Star grips also have a number of advantages. The star-shaped structure of star grips provides several grip points. This enables the user to execute more finely controlled rotational movements. The star grip also sits comfortably in the hand. This makes them suitable for applications where the grip has to be held for long periods, as it distributes the pressure more evenly.
In summary, it can be said that a palm grip is advantageous when high power transmission and rough adjustments are required. While the star grip is more suitable for finer adjustments and comfortable handling at low torque.
What are star grips?
Star grips are special operating elements that are widely used in mechanical engineering and manufacturing technology.
They are used to enable manual operation of machines, equipment and tools. The grips are characterised by a star-shaped or radially symmetrical design that provides even power transmission and good handling.
Star grips are also available as standard versions; the shape and dimensions of the grips are regulated by DIN 6336. It ensures that the grips are available in different sizes and shapes to meet the requirements of different applications.
In addition to the exact dimensions and the threads used for fastening, the standard also specifies the permissible materials.
Star grips are often made from durable materials such as plastic, aluminium, stainless steel or grey cast iron, which increases their longevity and resilience.
The standard also defines the surface finish, ensuring that the star grips offer a high level of grip and resistance to wear.
Different types of star grips enable different grips to be used depending on the application, such as models with a ribbed or rubberised surfaces for improved handling.

Triangular grips
Triangular grips are used in machine construction and industrial applications. The grip consists of three arms arranged symmetrically around a central point, thus forming the shape of a three-pointed star. This shape enables ergonomic handling and even force application.
The norelem range includes two different triangular grips. The triangular grip made from glass-bead reinforced thermoplastic is robust and durable. The cap is also made from thermoplastic and complements the grip.
The steel parts are grade 5.8, which ensures a sturdy and durable construction.
The grip and the cap are in an appealing black-grey (RAL 7021), which gives the component a modern and subtle visual appearance.
The triangular grip made from thermoset PF 31 is known for its high strength and dimensional stability.
The bush or threaded pin is available in either electro zinc-plated steel or bright stainless steel, with the stainless steel offering increased corrosion resistance.
The surface of these grips is highly polished, giving them a refined and elegant appearance.
Other external thread sizes, screw lengths and grip colours are available on request. This gives you additional flexibility for adaptations.
Five lobe grips
A five lobe grip is a special grip that was developed for manual controls in machine construction and industrial applications. It consists of five lobes that are arranged in a star shape, enabling even force distribution and safe handling.
The five lobe grip is often used as a twist knob or clamping grip to fixate components or adjust tools. Due to the ergonomic shape, it is easy to grip and can be operated with little effort. This makes it particularly useful for applications where precise adjustment or tightening is required.
Designs that our customers favour:
- Five lobe grips with internal thread
- Five lobe grips external thread
- Plastic lockable five lobe grips
- Colour coded five lobe grips
