Professional Applications & Engineering Value
These M5 socket head cap screws deliver critical engineering solutions where space constraints and high-strength requirements intersect. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the 140,000 psi tensile strength necessary for structural applications. The ultra-low profile socket head enables installation in tight clearances common in precision machinery, automotive assemblies, and industrial equipment. With Class 5g6g thread fit and coarse thread pitch, these metric fasteners ensure rapid assembly and reliable performance in high-vibration environments. The combination of Rockwell C32 hardness and precise length tolerance makes these screws ideal for repetitive manufacturing processes where consistency and durability are paramount.
Specification Summary & Compliance
Manufactured to precise metric standards with M5 x 0.8mm coarse threads and Class 5g6g thread fit tolerance. Features include 20mm length with ±0.127mm tolerance, 8.5mm head diameter, and 3mm hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel substrate provides corrosion resistance while maintaining mechanical properties for industrial fastener applications.
