Cold extrusion parts


When it comes to sophisticated parts and precision, BRUMA Schraub- und Drehtechnik GmbH as part of the Bossard Group is the right address for lightweight construction, highly stressed connections, new materials and material combinations.

As a specialist in fastening technology, we will find the perfect manufacturing solution for your component for your special applications in order to ensure your competitiveness. Product development and engineering are also closely linked with us.

In direct exchange with our customers, we support and advise on the basis of our engineering know-how and analyze parameters such as functions, geometries, tolerances, materials, costs and manufacturability in order to then select the appropriate manufacturing process.

Mechanical finishing, heat treatment and surface coating complete our offer. This guarantees you an efficient and sustainable production of your fastening element. Proof of this is provided by our special cold-forged parts, which have been installed millions of times in series applications.

We manufacture cold forged parts according to drawings or our own design. Our core products include special screws, bolts, bushings and torque limiters. At the customer’s request, we also manufacture customer-specific geometries and various surface finishes.

The required quality can then be ensured by implementing our zero-defect strategy using 100% sorting.
