From absolutely standards compliant to customized production: Screws, customized screws and special screws

Screws are the world’s most common and most versatile removable fasteners. Accordingly, many variations and special designs have evolved.

We manufacture screws, customised bolts und special screws in all shapes and head shapes from different materials and special materials. These include alloyed, non-alloyed and stainless steels, nonferrous metals such as aluminium and titanium or high-strength nickel alloys such as Hastelloy.

We create the right screw for each application. Special screws made out of titanium and high-strength aluminium for example, offer low weight and high stability. Safety screws with special heads that can only be opened with customized tools and reliably prevent unwanted tampering.
