Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot challenges in mechanical assemblies. The precision-machined 110mm shoulder acts as a shaft or bearing surface, eliminating the need for separate spacers and reducing component count. Manufactured from 316 Stainless Steel, it offers exceptional resistance to chemicals and saltwater corrosion, making it perfect for marine, chemical processing, and food machinery applications. The coarse pitch metric thread and Class 5g6g tolerance ensure quick, secure fastening in high-vibration environments. The hex socket head provides a flush profile and high torque capability, which is essential for compact designs and maintenance-free operation in automated systems and precision instruments.
