Professional Applications & Engineering Value

These M10 metric flat head screws deliver critical engineering solutions for heavy-duty industrial applications where failure is not an option. The zinc-plated alloy steel construction provides essential corrosion protection in manufacturing environments exposed to moisture, chemicals, or outdoor elements. The Class 12.9 strength rating ensures reliable performance in high-vibration machinery, structural assemblies, and equipment requiring sustained clamping force. The hex drive design allows for high-torque installation without cam-out issues, while the fully threaded configuration maximizes engagement in thick materials. Meeting DIN 7991 specifications, these metric screws provide standardized compatibility for European machinery and equipment designs requiring precise right-hand coarse threading with consistent performance.

Specification Summary & Compliance

This M10 flat head screw features precise Class 5g6g thread fit tolerance according to metric standards, ensuring proper engagement with mating components. The fastener complies with DIN 7991 manufacturing specifications for dimensional accuracy and performance requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restricted substance adherence for international industrial applications. The combination of 170,000 PSI tensile strength, Rockwell C39 hardness, and standardized metric threading (M10 x 1.5mm) provides reliable mechanical properties for critical fastening applications.
