Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 316 stainless steel material provides exceptional resistance to chemicals and moisture, making it suitable for medical devices, marine equipment, and food processing machinery. With a Class 5g6g thread fit and coarse M2 x 0.4mm metric thread, it ensures quick, reliable fastening while minimizing the risk of cross-threading. The black oxide finish enhances surface hardness and reduces friction, extending the screw's lifespan in high-cycle applications. The knurled head and hex socket drive allow for efficient torque transmission, reducing installation time and improving maintenance workflows in automated systems.
Specification Summary & Compliance
This shoulder screw features a metric M2 x 0.4mm coarse thread with Class 5g6g tolerance for precise fit. Key dimensions include a shoulder diameter of 3 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 7 mm (tolerance: 0 to 0.25 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity in industrial use.
