Professional Applications & Engineering Value
These M3 metric screws with a flanged hex button head address common industrial challenges like vibration loosening and alignment issues. Made from 6061 Aluminum with Rockwell B40 hardness, they offer an optimal balance of strength and weight savings, critical in aerospace, electronics, and automotive sectors. The coarse pitch (0.5mm) and Class 6g thread facilitate rapid assembly in soft materials or pre-tapped holes, while the wide rounded head and integrated flange enhance stability without needing separate washers. This design minimizes maintenance and improves longevity in dynamic environments, supporting efficient B2B procurement for high-volume projects.
Specification Summary & Compliance
This screw adheres to Metric system standards with precise dimensions: M3 x 0.5mm pitch, 8mm length, and Class 6g thread fit for consistent ISO-compatible tolerances. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(b)-II for lead in aluminum alloys and REACH (EC 1907/2006) regulations, ensuring safe, restricted-substance-free components for industrial use.
