Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and corrosion-induced failure. The 316 Stainless Steel material provides exceptional resistance to chemicals and moisture, crucial for industrial applications in electronics, machinery, and medical devices. The hex socket head with a knurled texture ensures reliable torque transmission, minimizing wear on tools and fasteners during repeated maintenance. With a Class 5g6g thread and coarse metric thread pitch, it offers quick, secure fastening that withstands vibrations and dynamic loads. The precisely machined shoulder (3 mm diameter) acts as a built-in spacer, simplifying assembly and enhancing structural integrity in compact designs.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M2 x 0.4 mm coarse thread size and Class 5g6g thread fit for consistent dimensional accuracy. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise component alignment. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
