Professional Applications & Engineering Value
These M3 metric screws with Class 10.9 strength and rounded head design are engineered to address critical fastening challenges in industrial machinery, automotive assemblies, and electronic enclosures. The blue-dyed zinc-plated alloy steel provides a protective barrier against oxidation and chemical exposure, significantly reducing maintenance cycles. The 2 mm hex drive enables secure, high-torque installation without cam-out, while the fully threaded coarse pitch ensures rapid assembly and superior resistance to loosening under dynamic loads. Ideal for applications requiring high-strength fasteners with precise ISO 7380 compliance, these screws deliver consistent performance in vibration-prone environments, minimizing downtime and enhancing operational reliability.
Specification Summary & Compliance
This M3 x 0.5 mm screw features a Class 6g thread fit with coarse spacing, ensuring dimensional accuracy per ISO 7380 standards. The fastener is manufactured from alloy steel with a Class 10.9 strength grade, supporting tensile loads up to 140,000 psi. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material traceability for industrial and export applications.
