The whole world of cold forming.

Our world

No, we don’t screw things up. On the contrary. But yes, at HEMA everything revolves around these small metal parts that everybody knows and that are so versatile. Why is that so? Quite simply - because we feel very strongly about screws!

Our development

Established almost 75 years ago, HEMA ranks among the leading companies for sophisticated metal forming technology. After decades of family ownership, the company now belongs to the Keller & Kallenbach group but always remains true to its regional roots and identity. You can rely on HEMA!

The Green Screw

Working hard. Gentle to the environment.

No wonder others turn green with envy. We from HEMA have been tinkering with the future, and this for quite a while. The Green Screw works hard but is gentle to the environment. Thus, it is the symbol of all our efforts in the field of sustainability.
