Professional Applications & Engineering Value
Engineered for industrial applications requiring both corrosion resistance and structural integrity, these 316 stainless steel flat head screws solve critical fastening challenges in marine, chemical processing, and food equipment installations. The passivated finish enhances surface durability against chlorides and acidic environments, while the M3 metric coarse thread with Class 6g tolerance ensures vibration-resistant connections in sheet metal, plastics, and machinery assemblies. The fully threaded design maximizes grip length in thin materials, and the hex drive configuration provides torque stability during high-volume production. Compliant with DIN 7991 specifications, these screws deliver consistent performance in automated assembly systems where precision and corrosion prevention are paramount.
Specification Summary & Compliance
Manufactured to DIN 7991 standards with Class 6g thread fit tolerance and metric coarse threading (M3 x 0.5mm pitch). Head diameter maintains -0.3 to 0 mm tolerance for precise countersinking. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Right-hand threaded with 30mm length and 90° countersink angle per industrial flat head screw specifications.
