Professional Applications & Engineering Value

These M5 socket head cap screws deliver exceptional engineering value for demanding industrial applications where failure is not an option. The Black-Oxide alloy steel construction provides superior corrosion resistance while maintaining the Class 12.9 strength rating required for heavy machinery, automotive assemblies, and precision equipment. The partially threaded design with 22mm minimum thread length ensures optimal clamping force distribution, preventing joint loosening under vibration. The 4mm hex drive and standard socket head profile allow for high-torque installation in confined spaces, making these metric coarse thread fasteners ideal for production lines, maintenance operations, and OEM equipment manufacturing where reliability and compliance with international standards are paramount.

Specification Summary & Compliance

This socket head cap screw features precise Class 5g6g thread fit tolerance per ISO metric standards with M5 x 0.8mm coarse thread spacing and right-hand thread direction. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental responsibility and regulatory acceptance for industrial applications worldwide.
