Strength Lives in the Connection

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.

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.

Increased

Strength

The continuous grain flow created during cold forming increases material strength and load capacity. Components maintain their structural integrity even under demanding mechanical loads.
Consistent

Precision

Cold forming enables repeatable geometries and consistent dimensional accuracy.
This is essential for tight tolerance chains and controlled tolerance stack-ups in safety-critical assemblies.
Material

Flexibility

Whether steel, stainless steel or special alloys - the cold extrusion process enables us to produce bolts from a wide variety of materials.
High

Material Efficiency

Cold forming uses nearly the entire material input.
This reduces material waste and improves resource efficiency.
Excellent

Surface Quality

Cold-formed surfaces are smooth and dimensionally precise.
This reduces friction and improves the reliability of mechanical connections.
No Mechanical

Post-Processing

Cold-formed bolts are typically ready for assembly.
In many cases, no additional machining is required.
Design

Flexibility

Whether delicate geometries or complex shapes, our bolts can be manufactured in a wide range of configurations tailored precisely to your requirements.
Secure

Connections

Our bolts create durable mechanical connections that maintain structural integrity even under high mechanical loads.

Connections Industries Rely On

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.

Kaltfließgepresster Exzenterbolzen | Bolzen | MN Kaltformteile
  • 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.

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.

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.
