Professional Applications & Engineering Value

These Class 10.9 metric hex socket button head screws deliver critical engineering solutions where space constraints meet high-strength requirements. The blue zinc-plated alloy steel construction provides essential corrosion protection for industrial equipment, machinery assemblies, and outdoor applications exposed to harsh environments. The M4 x 0.7mm coarse thread configuration ensures rapid installation while maintaining vibration resistance, making these fasteners ideal for production lines requiring efficiency and reliability. The rounded button head profile with 2.5mm hex drive offers a low-profile solution that prevents snagging in automated systems while providing sufficient torque capability. These characteristics make them particularly valuable in electronics enclosures, precision instruments, and mechanical assemblies where both aesthetic appeal and structural integrity are paramount.

Specification Summary & Compliance

Manufactured to exacting ISO 7380 standards with Class 6g thread fit tolerance for precision mating components. The fully threaded M4 x 0.7mm coarse pitch design maintains consistent engagement across the entire 12mm length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. The Class 10.9 strength rating with 140,000 psi tensile strength and Rockwell C32 hardness certification guarantees mechanical performance for critical applications.
