• High-strength performance with a Rockwell B79 hardness and 70,000 psi tensile strength for reliable load-bearing applications
• Secure, slip-resistant fastening using the internal 1.5mm hex drive for high-torque assembly and disassembly
• Accurate and consistent threading with a Class 6g thread fit and coarse M2 x 0.4mm pitch for easy installation and vibration resistance
• Compliance with global environmental standards, including RoHS 3 and REACH, ensuring safe use in regulated industries
• Optimized for automated assembly due to the standard socket head profile and consistent metric dimensions

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 316 stainless steel construction, enhanced by a passivated finish, provides exceptional resistance to chemicals, moisture, and oxidation, making it ideal for machinery, medical devices, and marine equipment. The 10mm shoulder length with precise tolerances acts as a reliable pivot or spacer, minimizing part movement and reducing wear on connected components. Combined with the Class 6g thread fit and coarse thread pitch, it ensures quick, secure fastening that withstands vibrations and dynamic loads. The internal hex drive allows for compact design and efficient torque application, streamlining assembly in confined spaces.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.025 to 0 mm and a shoulder length tolerance of 0 to 0.05 mm. The M2 x 0.4mm thread conforms to Class 6g fit for consistent engagement. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
