Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment challenges in machinery, automation, and precision equipment. The 40mm shoulder length with precise fit tolerance provides a stable bearing surface, reducing wear and misalignment in rotating assemblies. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical-exposed settings, extending service life. The low-profile socket head allows for compact designs and secure fastening in tight spaces, while the Class 6g thread fit and coarse thread spacing ensure quick, reliable installation. Ideal for use in industrial robots, conveyor systems, and electronic enclosures, this screw delivers consistent performance under high-stress conditions, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to metric standards with an M6x1 thread size, Class 6g thread fit, and precise shoulder dimensions (diameter tolerance: -0.025 to 0 mm; length tolerance: 0 to 0.05 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The manufacturing process focuses on durability, with a right-hand thread direction and coarse spacing for efficient assembly in industrial applications.
