Professional Applications & Engineering Value
This M4 shoulder screw is engineered from 316 stainless steel to deliver exceptional corrosion resistance, making it perfect for applications in chemical processing, marine equipment, and food machinery where moisture and corrosive agents are prevalent. The passivated finish enhances surface protection, while the Class 6g thread fit and precise shoulder dimensions ensure minimal backlash and reliable alignment in assemblies like pivots, gears, and rotating components. Its socket head with hex drive allows for compact installation in tight spaces, reducing the risk of stripping and improving maintenance efficiency. By combining high tensile strength and metric coarse thread, this screw addresses common issues of vibration loosening and misalignment, providing long-term reliability in industrial shoulder screw applications.
Specification Summary & Compliance
The screw features a Class 6g thread fit with M4 x 0.7mm coarse thread and precise shoulder diameter tolerance of -0.025 to 0 mm. It adheres to metric standards and is manufactured to ensure consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety requirements for industrial use.
