Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 Stainless Steel material offers inherent corrosion resistance, making it suitable for automotive, machinery, and electronic applications where exposure to moisture or chemicals is a concern. The 18 mm shoulder length and precise diameter tolerances act as a pivot or bearing surface, eliminating the need for additional spacers and reducing part count. Combined with a knurled socket head and coarse thread pitch, it ensures quick, secure installation in high-vibration environments, minimizing downtime and improving overall assembly integrity for industrial fasteners requiring reliable performance.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise engineering applications. It conforms to ISO 7379 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
