Why a European supplier
With our own production in the EU, we provide a stable supply chain, shorter logistics routes and direct technical support. Our goal is long-term cooperation with manufacturers who need a reliable supplier of mechanical components for series production – not a one-off delivery.
What we make
- Standard screws to DIN and ISO.
- Custom screws made to your drawing – adapted head shapes, drives and thread profiles. See Custom screws.
- Screws for wood, chipboard and plastics – thread geometry adapted to the material.
- Screws with washers, plus small packs and assembly kits.
- Steel and stainless steel – property classes 4.8, 8.8, 10.9 and 12.9; A2 and A4 for stainless versions.
The full range is on the Product range page.
How we keep large batches stable
Production is based on cold forming and thread rolling. Machines and measuring instruments are connected to a central measuring station (CAQ), we use statistical process control (SPC) on critical dimensions, and every batch is traceable from incoming material to delivery. For more demanding projects we add optical sorting and inspection of each packaging unit. Details are on the Quality & certificates page.
Who we work with
An important share of our projects are volumes of tens of millions of pieces for European OEM and Tier 1 manufacturers. Industry-specific information is on the Industries page.
