Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical challenges in precision assembly, such as maintaining alignment in compact mechanisms and resisting loosening under dynamic loads. The 18-8 stainless steel material, combined with a passivated finish, provides excellent corrosion resistance, making it suitable for electronics, medical devices, and automotive components exposed to moisture or chemicals. The ultra-low profile socket head minimizes protrusion, allowing for sleek designs without compromising strength. With a Class 6g thread fit and precise shoulder dimensions, it ensures minimal play and reliable performance in high-vibration environments, reducing maintenance needs and enhancing product longevity.
Specification Summary & Compliance
This metric shoulder screw features an M2 x 0.4mm coarse thread with Class 6g thread fit per ISO standards, ensuring dimensional accuracy. The shoulder diameter is 3 mm with a tolerance of -0.03 to 0 mm, and shoulder length is 5 mm with a tolerance of 0 to 0.06 mm for precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible manufacturing practices.
