Professional Applications & Engineering Value
This M3 shoulder screw in 316 stainless steel addresses critical engineering challenges in precision assemblies, such as machinery, electronics, and automotive systems. The 10mm shoulder length with precise tolerances provides stable alignment for rotating parts, reducing wear and misalignment issues. The ultra-low socket head and 2mm hex drive facilitate secure fastening in tight spaces, while the Class 6g thread fit and coarse pitch ensure quick, reliable installation even in high-vibration environments. Combined with high tensile and shear strength, this screw offers long-term reliability for industrial applications demanding corrosion resistance and dimensional stability.
Specification Summary & Compliance
This shoulder screw adheres to metric standards with an M3x0.5mm coarse thread and Class 6g thread fit for precise engagement. The shoulder features a diameter of 4mm (tolerance: -0.025 to 0mm) and length of 10mm (tolerance: 0 to 0.05mm), ensuring accurate component positioning. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental and safety requirements in industrial use.
