Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M3 socket head cap screws address common challenges like space constraints and vibration-induced loosening. The black-oxide alloy steel construction offers superior durability against wear and mild corrosion, while the ultra-low profile head and 2mm hex drive facilitate easy access in compact assemblies such as robotics, automotive components, and electronic enclosures. With a coarse thread pitch of 0.5mm, these screws provide rapid installation and robust clamping force, reducing assembly time without sacrificing performance. Ideal for high-strength applications requiring precision metric screws, they deliver consistent reliability in machinery, automation systems, and precision tooling where Class 5g6g thread fit ensures minimal tolerance deviations.

Specification Summary & Compliance

This socket head cap screw adheres to metric system standards with an M3 thread size, 0.5mm pitch, and 6mm length (tolerance: -0.127mm to 0.127mm). The Class 5g6g thread fit conforms to ISO precision requirements for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for global industrial use.
