Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision machinery. The 316 stainless steel construction, combined with a passivated finish, offers exceptional resistance to chemicals, saltwater, and oxidation, making it perfect for industrial applications in food processing, marine equipment, and pharmaceutical manufacturing. The precise shoulder fit (6mm diameter with -0.025 to 0mm tolerance) ensures components like bearings, gears, and pulleys remain securely positioned, reducing misalignment and extending service life. With a Class 6g thread and coarse 0.8mm pitch, it enables rapid assembly while maintaining vibration resistance in high-stress environments, providing reliable performance in automation systems and precision instruments.
Specification Summary & Compliance
This metric shoulder screw features a Class 6g thread fit per ISO standards, with precise dimensional tolerances including shoulder diameter (-0.025 to 0mm) and shoulder length (8mm with 0 to 0.05mm tolerance). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industries worldwide.
