Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 316 stainless steel material offers exceptional corrosion resistance, making it ideal for medical devices, marine equipment, and chemical processing applications where exposure to moisture and chemicals is common. The metric socket head with a knurled texture ensures a firm grip during installation, reducing the risk of tool slippage and damage. The 7mm shoulder length provides a stable bearing surface, allowing for accurate pivoting or spacing in machinery, while the Class 5g6g thread fit maintains tight tolerances to prevent loosening under vibration. By combining high tensile strength with precise dimensions, this screw enhances the reliability and service life of industrial fastening systems.
Specification Summary & Compliance
This shoulder screw adheres to metric thread standards with M2 x 0.4mm coarse pitch and Class 5g6g thread fit for consistent performance. Key dimensional tolerances include a shoulder diameter of 3 mm (-0.072 to -0.01 mm) and shoulder length of 7 mm (0 to 0.25 mm). The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
