• Superior corrosion protection through zinc-flake coating, extending service life in harsh industrial and outdoor conditions
• Precise torque application enabled by 4mm hex drive and standard socket head profile, preventing tool slippage and damage
• Excellent fatigue resistance from Rockwell C37 hardness, maintaining structural integrity under dynamic loads
• Broad compatibility with M5 coarse threading (0.8mm pitch) and Class 5g6g fit for easy installation in standard metric applications
• Full-length thread engagement providing consistent clamping force along the entire 20mm length
• Regulatory compliance assurance meeting DIN 912 specifications plus RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This Class 12.9 socket head cap screw delivers critical engineering solutions where failure is not an option. The zinc-flake-coated alloy steel construction provides exceptional corrosion resistance that outperforms conventional plating methods, making it ideal for automotive assemblies exposed to road salts and industrial equipment operating in humid environments. The M5 fully threaded design with 0.8mm coarse pitch ensures rapid installation while maintaining vibration resistance in machinery subjected to constant operation. The 4mm hex drive interface allows for high-torque tightening in confined spaces, preventing rounding commonly experienced with standard fasteners. These socket head cap screws are engineered to withstand extreme mechanical stresses in precision engineering applications, from robotic actuators to heavy-duty manufacturing equipment, where dimensional stability and reliable performance are paramount.

Specification Summary & Compliance

Manufactured to DIN 912 standards with Class 5g6g thread fit tolerance ensuring precise dimensional accuracy. The M5 x 0.8mm coarse thread configuration provides optimal engagement in most industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, with material certification available upon request. The 20mm length and 8.5mm head diameter maintain consistent proportions for uniform load distribution across fastened components.
