Professional Applications & Engineering Value
This M4 shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The 316 stainless steel material, combined with a passivated finish, provides superior resistance to chemicals, moisture, and extreme temperatures, making it ideal for industrial machinery, medical devices, and marine equipment. The precisely machined 5mm shoulder diameter acts as a reliable pivot or axle, eliminating misalignment in gears, pulleys, and linkages. With its hex socket head and Class 6g thread fit, it ensures vibration-resistant fastening in high-stress applications, reducing maintenance downtime and enhancing operational reliability.
Specification Summary & Compliance
This metric shoulder screw adheres to ISO metric thread standards with M4x0.7 coarse right-hand threads and Class 6g tolerance for precise fit. The shoulder features a diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm, ensuring consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material transparency for global supply chains.
