A DIN 933 A4 set screw is a fully threaded hexagon head fastener made from A4 stainless steel, also known as 316 or "marine grade." The addition of molybdenum gives A4 steel superior resistance to chlorides compared to A2 stainless steel, making these fasteners suitable for harsh environments including marine applications, chemical processing, and coastal construction.
