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 offers excellent resistance to rust and corrosion, making it suitable for machinery, automotive, and electronics where exposure to moisture or chemicals is common. The precise shoulder diameter of 8mm and 7mm shoulder length with minimal tolerances ensure accurate positioning of components, reducing misalignment and wear. Combined with a 4mm hex drive and coarse metric thread, it allows for efficient installation in high-volume production lines. The Class 6g thread fit and right-hand thread direction provide secure fastening, minimizing loosening under vibration, while the smooth head texture enhances aesthetics and functionality in assembled products.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with an M6x1mm thread size and Class 6g thread fit for precise tolerance. The shoulder diameter tolerance is -0.025 to 0 mm, and shoulder length tolerance is 0 to 0.05 mm, ensuring high accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental safety in industrial use.
