Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery exposed to moisture or chemicals. The 25 mm shoulder length with precise diameter tolerances ensures accurate positioning of moving parts, such as in precision assemblies, pivots, and rotating mechanisms, reducing wear and misalignment. The knurled socket head with a 4 mm hex drive facilitates secure tool engagement, speeding up installation in confined spaces. By integrating a coarse thread pitch and Class 5g6g thread fit, this screw minimizes assembly time and enhances reliability in high-vibration environments, supporting efficient production and maintenance workflows.

Specification Summary & Compliance
