Professional Applications & Engineering Value

These M10 flat head screws deliver critical performance in corrosive industrial settings where fastener failure is not an option. The 316 stainless steel material combined with passivated finish creates a protective barrier against chemicals, saltwater, and extreme temperatures, significantly extending service life in marine, chemical processing, and food industry applications. The fully threaded design with coarse pitch ensures rapid installation and superior holding power in various substrates, while the DIN 965 standardization guarantees precise dimensional accuracy for replacement and OEM requirements. The flat head profile with 90° countersink provides seamless surface integration, eliminating protrusions in machinery, enclosures, and structural assemblies where aerodynamic or aesthetic considerations are paramount.

Specification Summary & Compliance

This metric fastener features Class 6g thread fit tolerance per ISO standards, ensuring precise thread engagement and interchangeability. Manufacturing conforms to DIN 965 specifications for dimensional accuracy, including 18mm head diameter, 20mm length, and standardized Phillips No. 4 drive. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, confirming absence of restricted hazardous substances. The coarse thread spacing (1.5mm pitch) provides optimal performance in most industrial materials while the fully threaded design maximizes grip length across the entire shank.
