- Regulatory Compliance – Meets RoHS 3 and REACH standards for safe use in regulated industries
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 base material combined with TiCN coating creates an optimal surface for applications requiring both corrosion resistance and reduced friction. The 8mm shoulder diameter with precise tolerance control ensures perfect concentricity in bearing mounts and rotating assemblies, eliminating misalignment issues. With Class 6g thread fit and coarse thread pitch, these metric shoulder screws maintain secure fastening under dynamic loads while the hex socket drive enables efficient installation in confined spaces common in industrial equipment.
Specification Summary & Compliance
Manufactured to exacting standards with Class 6g thread fit per metric specifications, featuring M6x1mm coarse thread with 11mm thread length. Shoulder dimensions maintain precise tolerances: diameter -0.025 to 0 mm and length 0 to 0.05 mm. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability.
