Metric Stainless A4 70 Hex HD Screw, DIN 933
Our Metric Stainless Steel A4‑70 Hex Head Screws manufactured to DIN 933 are high‑quality, corrosion‑resistant fasteners designed for demanding industrial, marine, and outdoor applications. Made from A4 stainless steel (316 equivalent) and rated to property class A4‑70, these screws provide reliable tensile strength along with superior resistance to chlorides, saltwater, chemicals, and harsh environmental exposure.
The DIN 933 standard specifies a fully threaded hex head screw, offering consistent thread engagement along the entire length for uniform clamp load and installation flexibility. The hex head design allows efficient torque application with standard metric tools, making these fasteners suitable for structural assemblies, equipment manufacturing, piping supports, and mechanical installations where stainless performance and European dimensional standards are required.
Engineered for durability and precision, A4‑70 Stainless Hex Head Screws (DIN 933) are commonly used in marine construction, chemical processing facilities, wastewater treatment systems, food and beverage operations, and outdoor structural installations. The A4 stainless material delivers superior corrosion resistance compared to A2 (304) stainless, while the 70 strength class provides dependable mechanical performance for general‑purpose and load‑bearing assemblies. Available in a wide range of metric diameters and lengths, DIN 933 hex head screws offer consistent quality and long service life in corrosive and moisture‑exposed environments.
