• High-strength performance delivering 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing applications
• Secure, non-slip installation with knurled hex socket head design and 2mm drive for improved torque transmission
• Consistent thread engagement ensured by Class 5g6g metric coarse threads with 0.4mm pitch
• Extended service life from Rockwell B79 hardness, resisting wear in high-cycle operations
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global supply chain integration

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 316 Stainless Steel material combined with black oxide finish provides exceptional resistance to chemicals, moisture, and oxidation, making it suitable for medical devices, optical equipment, and electronic enclosures. The 5mm shoulder length with controlled tolerances acts as a precise pivot or spacer, minimizing part misalignment and reducing bearing wear. The knurled hex socket head ensures secure tool engagement during installation in confined spaces, while the Class 5g6g coarse thread facilitates faster assembly without compromising mechanical integrity. These features collectively enhance equipment reliability and reduce maintenance downtime in demanding industrial applications.

Specification Summary & Compliance

This shoulder screw features M2 x 0.4mm coarse pitch threads manufactured to Class 5g6g tolerance for consistent fit. The shoulder diameter tolerance is -0.072 to -0.01 mm with shoulder length tolerance of 0 to 0.25 mm, ensuring precision in assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for regulated industries and international markets.
