Professional Applications & Engineering Value
This M3 flat head screw is engineered to solve critical challenges in industrial and marine applications where corrosion resistance is paramount. The 316 stainless steel material and passivated finish provide an exceptional barrier against chlorides and chemicals, significantly extending service life in aggressive environments. The fully threaded design and Class 6g metric thread ensure precise, secure fits in pre-tapped holes, reducing the risk of loosening under vibration. The 90° countersink and flat head create a smooth, flush surface, ideal for applications in machinery, electronic enclosures, and structural assemblies where protrusions are not permissible. Its combination of high tensile strength and standardized DIN 7991 dimensions makes it a reliable, high-performance industrial fastener for OEMs and MRO professionals.
Specification Summary & Compliance
This screw conforms to the dimensional and tolerance specifications of DIN 7991. The metric thread is M3 x 0.5 mm with a Class 6g tolerance fit. Key dimensional tolerances include a head diameter of 6 mm with a tolerance of -0.3 to 0 mm. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances.
