• Precise thread engagement with Class 5g6g thread fit ensuring consistent, secure fastening and vibration resistance
• Optimized low-profile design featuring an ultra-low socket head for applications with limited clearance space
• Easy installation and removal using standard 3mm hex tools, reducing assembly time and maintenance efforts
• Reliable coarse thread performance with 0.8mm pitch providing excellent holding power and resistance to loosening
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable industrial use

Professional Applications & Engineering Value

These M5 socket head cap screws deliver exceptional engineering value in industrial applications where space constraints and corrosion resistance are critical concerns. The black-oxide alloy steel construction provides superior protection against environmental degradation while maintaining high tensile strength for structural integrity. The ultra-low head profile enables installation in tight spaces where standard fasteners cannot fit, making them ideal for precision machinery, automotive assemblies, and electronic enclosures. The Class 5g6g thread fit ensures precise mating with corresponding nuts and tapped holes, preventing cross-threading and ensuring consistent clamp load distribution. With their coarse thread design and robust material properties, these screws effectively resist vibration-induced loosening while providing quick assembly in production environments requiring high-volume fastening operations.

Specification Summary & Compliance

This metric socket head cap screw features M5 x 0.8mm coarse threads with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. The 12mm length maintains tight tolerances of -0.127mm to 0.127mm for consistent performance. Manufactured from high-strength alloy steel with black-oxide surface treatment, the fastener delivers 140,000 psi tensile strength and Rockwell C32 hardness. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring certified components.
