• Corrosion-resistant black-oxide finish on alloy steel provides enhanced protection against environmental factors in harsh operating conditions
• Optimized coarse thread pitch (0.8mm) enables faster installation and reduced cross-threading risk compared to fine-pitch alternatives
• Consistent dimensional accuracy with length tolerance of ±0.127mm ensures uniform performance across production runs
• Environmental compliance assurance with RoHS 3 and REACH regulations for use in regulated industries and international markets

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 combined with Rockwell C32 hardness addresses common industrial challenges including vibration-induced loosening and material fatigue in machinery, automation systems, and precision equipment. The ultra-low profile head design is particularly valuable in compact assemblies where standard fastener heads would interfere with adjacent components. The coarse 0.8mm pitch metric thread provides superior engagement in both metallic and composite materials, while the Class 5g6g thread fit ensures consistent clamping force distribution across critical joints. These fully threaded fasteners maintain their integrity through repeated disassembly cycles, making them ideal for maintenance-intensive industrial applications.

Specification Summary & Compliance

This metric socket head cap screw features precise M5 x 0.8mm coarse threading with Class 5g6g thread fit per ISO metric standards, maintaining length tolerance of -0.127mm to +0.127mm for dimensional consistency. Manufactured from alloy steel with black-oxide surface treatment, the fastener delivers 140,000 psi tensile strength for high-stress applications. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances, ensuring environmental responsibility and market accessibility.
