Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and fastening challenges in precision assemblies. The 316 Stainless Steel material provides excellent resistance to corrosion and chemicals, making it suitable for medical devices, food processing equipment, and marine applications. The integrated 5mm shoulder acts as a precise pivot, bearing surface, or locator, eliminating the need for additional spacers and reducing assembly complexity. The Class 5g6g thread and coarse pitch ensure quick and reliable threading into components, while the socket head with hex drive allows for high-torque installation in confined spaces. This design is ideal for securing gears, pulleys, and linkages where vibration resistance and dimensional accuracy are paramount.
