Professional Applications & Engineering Value

These M3 socket head cap screws with black-oxide alloy steel construction address critical engineering challenges in compact assemblies where space optimization and corrosion resistance are paramount. The ultra-low profile head design (1mm height) enables installation in tight spaces without compromising structural integrity, while the Class 5g6g thread fit ensures precise mating with components in precision machinery, automotive systems, and electronic enclosures. The combination of 140,000 psi tensile strength and Rockwell C32 hardness provides reliable performance in high-stress applications, preventing thread deformation and maintaining clamping force under vibration. The coarse thread pitch (0.5mm) facilitates quick assembly in production environments, making these metric hex socket screws ideal for manufacturing equipment, robotics, and industrial automation systems requiring repeated maintenance access.

Specification Summary & Compliance

This fully threaded M3 socket head cap screw features precision metric coarse threads with 0.5mm pitch and Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy within length tolerance of -0.127mm to 0.127mm. Manufactured from alloy steel with black-oxide surface treatment for enhanced corrosion protection, these fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring strict material compliance.
