We supply thin and long screws as reduced shank screws (DIN 7964) with reduced shank, thin shank or machined shank.

Reduced shank screws according to DIN 7964 and machined, also in small batch sizes

Reduced shank screws and long shank screws have a shank between head and thread which is thinner than the thread. They offer the possibility of dismantling parts in such a way that the screws are left hanging in the part and cannot be lost. By machining blanks, we can also manufacture small batch sizes with different shank lengths at low cost.
