Professional Applications & Engineering Value

These M6 flat head screws deliver critical engineering advantages where corrosion resistance and structural integrity are paramount. Manufactured from 316 stainless steel with a passivated finish, they effectively combat chloride-induced stress corrosion cracking in marine, chemical processing, and food industry applications. The metric coarse threading (M6 x 1mm) with Class 6g tolerance ensures rapid installation and secure fastening in metals, plastics, and composite materials. The fully threaded design provides consistent clamping force across the entire 50mm length, while the Phillips No. 3 drive offers reliable torque transmission for production line efficiency. These flat head screws solve common industrial challenges including vibration loosening, material compatibility issues, and environmental degradation.

Specification Summary & Compliance

This metric screw features precise M6 x 1mm coarse threading with Class 6g thread fit tolerance according to DIN 965 specifications. The manufacturing process ensures dimensional accuracy for the 11mm head diameter, 3mm head height, and 50mm overall length. These industrial fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances. The passivated surface treatment enhances the natural corrosion resistance of 316 stainless steel, while maintaining the mechanical properties including the specified 70,000 psi tensile strength.
