In the beginning there were: man, his hammer and a rivet head maker (riveting die).

Riveting as one of the oldest methods of connecting two components in an inseparable way is already known since early history.

Riveted unions were produced by peening bolt rivets over with a hammer.

As industrialisation was on the rise, also presses or mechanical hammers for metal working were gaining ground but were soon replaced by specific riveting machines. The great amount of force to be exerted along with high noise levels on the one hand and, on the other hand, the changes in the structure of the rivets and their embrittlement were less and less accepted by users who demanded higher quality standards.

Though the orbital riveting technology did bring some improvements in its wake, the hardenings of the rivet structure and the damage to the closing head surface still remained.

The invention that revolutionised the riveting world

The Radial Point Riveting Technology by Friedrich

In the year 1966, Friedrich's engineers layed the foundation for a technology which to this date remains the most efficient and economic one:

The Friedrich Radial Point Riveting Technology

The advantages of the radial point riveting technology:

• low effort combined with a high riveting power
• low-noise and uniform rivet shaping
• low transverse forces, therefore workpiece fastening is easy
• particularly suited to meet quality assurance requirements due to the vertical riveting die
• minimum friction, little heat development and a smooth rivet surface
• gentle change to the rivet material structure
• no rotation of the die, therefore also stamping is possible
• allows to achieve an easily dimensionable  bearing stress

These microsections show the differences in structural conditions obtained by the different riveting methods for shaping the rivets. It is with the radial point riveting method only that the material structure remains unchanged to the greatest possible extent.
