316 stainless steel DIN912 screws are precision industrial fasteners, fully compliant with the DIN912 German standard for dimensional accuracy and reliable performance. Designed with extended half threads, cylindrical/cup heads, and internal hex sockets, they cover metric sizes M5-M20*30-150, making them ideal for heavy machinery, chemical equipment, marine applications, and harsh environments requiring high corrosion resistance and secure fastening.
Crafted from premium 316 stainless steel, these screws offer superior corrosion, rust, and chemical resistance—excellence in saltwater, humid, and chemical-exposed settings compared to standard 304 grade. The extended half thread design balances strong threading engagement and smooth shank stability, while the internal hex socket enables secure torque control and slip-proof installation with standard tools. The cylindrical/cup head provides a low-profile, uniform finish, protecting workpieces and ensuring seamless integration into industrial assemblies.
