• Enhanced corrosion resistance through blue-dyed zinc plating on alloy steel, extending service life in industrial environments
• Precise installation and removal with 3mm hex drive design providing secure tool engagement and reduced stripping risk
• Optimal thread engagement with fully threaded M5 coarse pitch (0.8mm) design for faster assembly and strong holding power
• Streamlined profile with rounded button head that minimizes protrusion while maintaining high clamp force distribution
• Consistent dimensional accuracy meeting ISO 7380 specifications for reliable interchangeability across applications
• Environmental compliance assurance with RoHS 3 and REACH regulations for sustainable manufacturing practices

Professional Applications & Engineering Value

These Class 10.9 metric button head socket cap screws deliver exceptional engineering value through their blue-dyed zinc-plated alloy steel construction, specifically engineered to withstand high vibration and dynamic loading conditions common in industrial machinery, automotive assemblies, and precision equipment. The fully threaded M5 coarse pitch design ensures maximum thread engagement in both thick and thin materials, while the rounded head profile eliminates sharp edges that could damage surrounding components. The 3mm hex drive provides superior torque transmission compared to standard screw heads, reducing installation time and preventing tool slippage that can compromise fastener integrity. This combination of high tensile strength (140,000 psi) and Rockwell C32 hardness makes these fasteners ideal for applications requiring repeated disassembly without thread degradation.

Specification Summary & Compliance

Manufactured to ISO 7380 standards with Class 6g thread fit tolerance ensuring precise dimensional consistency. The 16mm length with fully threaded M5 x 0.8mm coarse pitch configuration provides reliable performance across various material thicknesses. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility, while the Class 10.9 strength rating guarantees mechanical performance meeting international engineering standards for industrial fastener applications.
