• Superior corrosion resistance thanks to black-oxide coating on alloy steel, extending service life in demanding conditions
• Maximum torque transmission through precision hex socket drive (2 mm) preventing stripping and ensuring secure fastening
• Optimal thread engagement with fully threaded M2.5 coarse pitch (0.45 mm) design for faster assembly and stronger holding power
• Precise dimensional accuracy meeting Class 5g6g thread fit standards for consistent performance and interchangeability
• Industry-standard compatibility with DIN 912/ISO 4762 specifications ensuring seamless integration into existing metric systems
• Environmental compliance with RoHS 3 and REACH regulations for safe use across global industrial applications

Professional Applications & Engineering Value

These M2.5 socket head cap screws deliver critical engineering solutions where space constraints and high tensile demands coexist. The black-oxide alloy steel construction provides essential corrosion protection in industrial environments while maintaining the 170,000 psi tensile strength required for machinery, automotive, and precision equipment applications. The fully threaded metric design with coarse pitch ensures rapid installation and maximum thread contact in thin materials, while the hex socket drive allows for high-torque tightening in confined spaces. Engineered to DIN 912/ISO 4762 standards, these Class 12.9 screws prevent joint failure in vibration-prone assemblies, making them ideal for critical fastening in manufacturing, robotics, and aerospace components where reliability is non-negotiable.
