Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical challenges in precision assemblies, such as in electronics, medical devices, and optical equipment. The 316 Stainless Steel material provides exceptional resistance to corrosion and oxidation, extending service life in humid or chemically aggressive settings. Its hex socket head and 2mm drive size facilitate secure torque application without stripping, while the coarse 0.4mm thread pitch ensures quick, stable engagement. The 20mm shoulder length with controlled tolerances acts as a precise pivot or spacer, reducing wear and maintaining alignment in dynamic systems. By integrating Class 5g6g threads, it guarantees consistent fit with mating parts, streamlining production and minimizing rework in automated or manual installations.

Specification Summary & Compliance

This shoulder screw adheres to Metric standards with a Class 5g6g thread fit for dimensional accuracy. Key specifications include a shoulder diameter of 3 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 20 mm (tolerance: 0 to 0.25 mm). It is manufactured to a hardness of Rockwell B79 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
