Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent corrosion resistance, extending service life in industrial settings like electronics, machinery, and automotive components. The 5mm shoulder diameter with precise fit tolerance ensures accurate positioning of parts, reducing vibration and wear. With a Class 6g thread and coarse pitch, it offers quick assembly and high resistance to loosening under dynamic loads. The hex socket head allows for compact tool access, making it suitable for confined spaces. Ideal for applications requiring reliable shoulder screw performance, it supports efficient production and long-term operational stability.
Specification Summary & Compliance
This shoulder screw adheres to metric thread standards with a Class 6g thread fit and coarse spacing (0.4mm pitch). Shoulder diameter tolerance is -0.025 to 0 mm, and shoulder length tolerance is 0 to 0.05 mm, ensuring precision fit in assemblies. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use.
