Reliable Fastening for Demanding Applications
Why Cold Extruded Bolts Deliver Superior Performance
Cold-formed bolts are manufactured to meet demanding technical requirements.
They offer high strength, precise geometries and reliable performance in automated series production.
Strength
Precision
This is essential for tight tolerance chains and controlled tolerance stack-ups in safety-critical assemblies.
Flexibility
Material Efficiency
This reduces material waste and improves resource efficiency.
Surface Quality
This reduces friction and improves the reliability of mechanical connections.
Post-Processing
In many cases, no additional machining is required.
Flexibility
Connections
Your Direct Path to a Technical Solution
We Turn Your Bolt Design into a Reliable Series Component
We analyse technical feasibility, optimise the forming process and develop solutions tailored precisely to your requirements.

More Strength, Less Material
How Cold Forming Reduces Material Consumption
Sometimes less material delivers more performance – especially in bolt manufacturing.
By using cold forming instead of turning, significant material savings can be achieved.
This process reduces material waste and improves overall resource efficiency.

Maximum Accuracy. Tight Tolerances.
The Perfect Fit for Precision Bolts
Cold forming enables even highly complex geometries with precision tolerances of up to 0.05 mm.
Using self-opening segmented tools (so-called jaw tools), we can efficiently form bolts with intermediate collars or reduced shank sections between larger diameters.
Customised Solutions Through a Wide Range of Materials
Bolt Quality
Begins With Material Selection
Material selection defines the strength and performance of a bolt.
We offer a wide range of materials to match your requirements:
| Material: | Properties: |
|---|---|
| Copper | Particularly suitable for electrical and electronic applications thanks to its excellent electrical conductivity. |
| Stainless Steel | Designed for demanding operating conditions due to its outstanding corrosion resistance and durability. |
| Brass | This material offers self-lubricating properties (emergency running capability), ensuring a long service life. |
| Aluminium | Lightweight yet stable – ideal for constructions where weight reduction is important. Depending on the alloy, additional heat treatment can further increase strength. |
| Steel | Provides high strength – the ideal choice for applications subject to heavy loads. |
| Special Alloys | Customised materials for specific technical requirements and demanding environments. |
Shaped Under Pressure. Strengthened by the Process.
Whether Bolts or Biceps - Real Strength Comes From Pressure
From standard parts to complex custom designs, we manufacture cold-formed bolts engineered for demanding applications.
They deliver high strength, precise geometries and reliable performance in automated series production.

What Is a Bolt?
A bolt is a rotationally symmetric fastener with a head or collar designed to join and secure components.
In mechanical and mechatronic assemblies, bolts ensure reliable positioning, load transfer and structural stability.
Engineered for a Wide Range of Applications
Key Functions of Bolts in Mechanical Systems
Bolts are more than simple fasteners – they are adaptable components engineered for a wide range of applications.
From mechanical engineering to automotive systems, each bolt type offers specific properties tailored to its intended function.
- Connection and fastening: Bolts securely join components and maintain a stable mechanical connection even under high loads.
- Rotating and bearing function: Some bolts act as pivot or bearing elements and allow controlled movement of components, as required in machines or vehicle mechanisms.
- Security function: In locking systems, bolts provide essential security functions by preventing mechanical components from being opened without authorisation.
- Precise setting and adjustment: Eccentric bolts enable precise adjustment, for example in window mechanisms, to achieve accurate sealing.
- Power transmission: In electrical applications, studs can be used as contact rivets to create reliable electrical connections and ensure efficient power transmission.
- Damping and relief function: Rubber- or plastic-coated bolts can reduce vibrations and shocks, helping to extend the service life of machines and vehicles.
