• Regulatory compliance assurance with RoHS 3 and REACH compliance for global manufacturing and environmental standards

Professional Applications & Engineering Value

Engineered for high-stress industrial applications, these M5 socket head cap screws deliver critical performance where failure is not an option. The alloy steel construction with Rockwell C37 hardness provides exceptional resistance to shear and tensile forces in machinery, automotive, and heavy equipment assemblies. The blue-dyed zinc-plated surface treatment offers both corrosion resistance and visual identification benefits in complex assemblies. With Class 5g6g thread fit and coarse thread pitch, these fasteners ensure rapid installation while maintaining vibration resistance in dynamic environments. The 4mm hex drive design allows for high torque application in confined spaces, making them ideal for precision equipment where access is limited but reliability is paramount.

Specification Summary & Compliance

This metric socket head cap screw features precise M5 x 0.8mm coarse threads with Class 5g6g tolerance and 20mm fully threaded length. Manufactured to DIN 912/ISO 4762 standards with 8.5mm head diameter and 5mm head height. The fastener meets Class 12.9 strength requirements with 170,000 PSI tensile strength and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global manufacturing applications.
