Professional Applications & Engineering Value

This M2 metric screw with black-oxide alloy steel construction addresses critical engineering challenges in precision assemblies. The Class 10.9 strength rating (140,000 PSI tensile strength) ensures reliable performance in high-vibration environments where fastener failure is not an option. The fully threaded design provides maximum thread engagement for superior clamping force in thin materials and tight spaces. The hex drive button head configuration offers both aesthetic appeal and practical installation advantages, allowing flush mounting while maintaining easy access with standard hex tools. These rounded head screws are particularly valuable in electronics, machinery, and automotive applications where corrosion resistance, consistent performance, and regulatory compliance are essential for long-term reliability and maintenance reduction.

Specification Summary & Compliance

This precision metric fastener features M2 x 0.4mm coarse threading with Class 6g thread fit tolerance ensuring precise engagement. Manufactured to ISO 7380 specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The 16mm length with fully threaded right-hand configuration provides consistent performance across industrial applications while maintaining the high Class 10.9 strength classification and Rockwell C32 hardness for durable, reliable fastening solutions.
