Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical assembly challenges in demanding industrial applications. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The integrated 12mm shoulder length acts as a precise pivot, axle, or spacer, minimizing misalignment and bearing surface wear in moving parts. Combined with the coarse thread (0.8mm pitch) and Class 5g6g thread fit, it ensures rapid, secure fastening and maintains joint integrity under vibration and dynamic loads. The socket head with a 3mm hex drive allows for compact installation in confined spaces, enhancing design flexibility and maintenance efficiency.
