Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in electronics, medical devices, and automation equipment where exposure to moisture or chemicals is common. The coarse 0.4mm pitch thread and Class 5g6g thread fit ensure quick, secure fastening with minimal risk of cross-threading, while the hex socket head and knurled texture facilitate easy handling in tight spaces. By providing a reliable shoulder for precise part location, this screw reduces assembly time and enhances the longevity of mechanical systems, supporting efficient production and maintenance cycles.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with precise dimensions: M2 thread size, 0.4mm coarse pitch, and a shoulder diameter of 4 mm with tight tolerances (e.g., shoulder diameter tolerance of -0.072 to -0.01 mm). The thread fit conforms to Class 5g6g, ensuring high accuracy for industrial use. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for global markets.
