Professional Applications & Engineering Value

These Class 12.9 socket head cap screws deliver critical performance in high-stress mechanical assemblies where failure is not an option. The black-oxide alloy steel construction provides superior protection against corrosion while maintaining the Rockwell C37 hardness required for repeated disassembly and reassembly cycles. The M5 coarse threading with Class 5g6g precision ensures rapid installation in production environments while resisting loosening under vibration - a common challenge in industrial machinery, automotive systems, and precision equipment. The combination of fully threaded design and 4mm hex drive allows for consistent clamping force distribution and reliable torque application, making these fasteners ideal for critical joints in manufacturing equipment, robotics, and heavy-duty applications where dimensional stability and repeatable performance are paramount.

Specification Summary & Compliance

This metric socket head cap screw features M5 x 0.8mm coarse threading with Class 5g6g thread fit tolerance per ISO standards. The 30mm fully threaded length provides complete engagement capability. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental and safety standards are maintained for industrial applications worldwide.
