Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in machinery assembly, automation systems, and precision instruments. The 18-8 stainless steel core provides excellent corrosion resistance while the TiCN coating dramatically reduces wear in high-cycle applications. The 6mm shoulder length with precise diameter control ensures accurate component positioning, eliminating misalignment issues in rotating assemblies and bearing mounts. With its M3x0.5mm coarse thread and Class 6g thread fit, this fastener delivers reliable performance in vibration-prone environments where maintaining precise clearances is essential for optimal machine operation and reduced maintenance downtime.
Specification Summary & Compliance
This metric shoulder screw features M3 thread size with 0.5mm pitch and Class 6g thread fit per ISO standards. The shoulder maintains precise dimensional control with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured from 18-8 stainless steel with TiCN coating, it achieves Rockwell B55 hardness and 70,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial applications worldwide.
