Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, while the black oxide finish adds an extra layer of protection against wear and galling. The precisely machined 10mm shoulder ensures accurate positioning of components such as gears, pulleys, and bearings, reducing vibration and misalignment issues. With a coarse thread pitch (0.8mm) and Class 5g6g thread fit, it offers quick assembly and reliable fastening in high-stress environments like machinery, automotive assemblies, and precision equipment. Its socket head design with a knurled texture allows for secure tool grip, facilitating maintenance and reducing downtime in production lines.

Specification Summary & Compliance
