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 provides excellent corrosion resistance, making it suitable for machinery, automotive assemblies, and electronic devices exposed to moisture or chemicals. The 100mm shoulder length with tight tolerances ensures precise positioning of moving parts, reducing wear and improving operational accuracy. The knurled socket head with a 4mm hex drive allows for secure, high-torque installation without stripping, while the coarse metric thread (M6x1mm) enables quick fastening in high-volume production. Its high tensile and shear strength support heavy-duty applications, offering long-term reliability and minimizing downtime in precision engineering projects.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 for dimensional accuracy, with a shoulder diameter of 8mm (tolerance: -0.072 to -0.01 mm) and length of 100mm (tolerance: 0 to 0.25 mm). Thread specifications include M6x1mm coarse thread with a Class 5g6g fit for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
