Professional Applications & Engineering Value
This M2 shoulder screw delivers critical engineering solutions where space constraints and precision alignment are paramount. The ultra-low profile socket head design minimizes protrusion in compact assemblies like robotics, medical devices, and optical equipment, while the 18-8 stainless steel material and passivated finish provide excellent corrosion resistance in demanding environments. The precisely machined 3mm shoulder diameter with tight tolerances ensures accurate component positioning, eliminating misalignment issues in rotating mechanisms and bearing mounts. With its Class 6g thread fit and 4mm thread length, it offers reliable fastening in thin materials and delicate components, making it ideal for electronics manufacturing and precision instrumentation where vibration resistance and dimensional stability are crucial.
Specification Summary & Compliance
This precision metric shoulder screw features M2 x 0.4mm coarse right-hand threads with Class 6g thread fit per ISO standards. The shoulder maintains precise dimensions with diameter tolerance of -0.03 to 0mm and length tolerance of 0 to 0.06mm. Manufactured from 18-8 stainless steel with passivated finish and hardened to Rockwell B97, it delivers 95,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions.
