Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. Made from 18-8 stainless steel, it offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronics where exposure to moisture or chemicals is common. The 80mm shoulder length provides a precise unthreaded section that acts as a pivot, spacer, or bearing surface, reducing wear on components and ensuring smooth rotational movement. With a knurled head and hex socket drive, it allows for secure, high-torque installation in confined spaces, minimizing the risk of stripping. The coarse thread and Class 5g6g fit enhance assembly efficiency and vibration resistance, ideal for dynamic applications. Compliant with ISO 7379, this metric shoulder bolt delivers consistent performance, reducing maintenance needs and downtime in precision assemblies.

Specification Summary & Compliance
