Professional Applications & Engineering Value
This M2 shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 30mm shoulder length with controlled tolerances provides a stable bearing surface, reducing wear and misalignment in rotating components like gears, pulleys, and linkages. Made from 18-8 stainless steel, it resists corrosion in moist or chemical-exposed settings, while the hex socket head and knurled texture allow for high-torque installation without slippage. The Class 5g6g metric thread with coarse pitch ensures quick assembly and reliable holding power in industrial applications such as electronics, machinery, and automotive systems, where precision and strength are paramount.
Specification Summary & Compliance
This shoulder screw features a metric M2 x 0.4mm coarse pitch thread with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for precise fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substances.
