Professional Applications & Engineering Value

This M2 shoulder screw delivers critical precision for industrial assemblies requiring exact component positioning. The 316 Stainless Steel material combined with Black Oxide finish provides exceptional resistance to chemicals, moisture, and extreme temperatures, solving corrosion-related failure points in marine, chemical processing, and outdoor equipment. The 8mm shoulder length acts as a precision spacer or pivot in machinery, maintaining alignment while the Class 5g6g thread fit ensures vibration-resistant fastening. Engineered for precision instruments, automation systems, and electronic enclosures, this metric shoulder screw eliminates the need for additional alignment components, reducing assembly time and improving structural integrity in compact designs.

Specification Summary & Compliance

This M2 x 0.4mm shoulder screw maintains Class 5g6g thread tolerances per metric standards with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications. The right-hand coarse thread spacing and standard shoulder fit provide consistent performance across automated assembly systems.
