  The  standard  material  of  our  screws  is stainless steel A2, the "classic“ AISI 304.
For especially corrosive medias or in case of needing a lower magnetizability, the  stainless steel A4 (AISI  316) can be used. Titanium and aluminum  can be  applied,  where  fasteners  should be  non-magnetizable. Thereby, the reduced strength of aluminum has to be considered.
