• Enhanced torque transmission and slip resistance from the knurled socket head and 2 mm hex drive, ensuring secure fastening.
• Precise component alignment and spacing enabled by the 4 mm diameter shoulder with controlled tolerances.
• High mechanical strength and durability with a tensile strength of 70,000 psi and Rockwell B79 hardness for demanding applications.
• Reliable and consistent thread engagement due to the Class 5g6g thread fit, reducing the risk of cross-threading.
• Broad industrial compliance with RoHS 3 and REACH regulations, ensuring environmental and safety standards are met.
• Optimized for coarse threading (0.4 mm pitch) facilitating quicker assembly and disassembly in maintenance operations.

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 provides exceptional resistance to chemicals and moisture, making it suitable for medical devices, food processing equipment, and marine applications. The integrated 4 mm shoulder acts as a precise pivot or spacer, eliminating the need for additional components and reducing assembly errors. The knurled socket head combined with a 2 mm hex drive ensures maximum torque is applied without tool slippage, which is vital for maintaining integrity in high-vibration environments. Its Class 5g6g thread guarantees a secure fit, preventing loosening and ensuring long-term reliability in automated machinery and precision instruments.

Specification Summary & Compliance

This precision shoulder screw adheres to Metric standards with an M2 x 0.4 mm coarse thread and a Class 5g6g thread fit for dimensional accuracy. The shoulder diameter is manufactured to a tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to 0.25 mm, ensuring consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial and electronic applications requiring stringent environmental and safety standards.
