Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and pivot point challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to chemicals and corrosion, making it perfect for medical devices, food processing equipment, and marine applications. The long, 50mm shoulder acts as a precise spacer or axle, eliminating the need for additional bushings and reducing assembly complexity. The knurled socket head with a 2mm hex drive ensures a firm grip, preventing tool slippage during installation in tight spaces. Its Class 5g6g thread fit guarantees consistent performance in metric assemblies, providing reliable fastening where vibration resistance and positional accuracy are paramount.
