Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in industrial applications where precision, strength, and corrosion resistance are paramount. The 316 stainless steel material provides excellent resistance to chemicals and moisture, making it suitable for machinery, automotive assemblies, and marine equipment. The 25mm shoulder length acts as a precise pivot, spacer, or bearing surface, reducing wear on components and ensuring accurate alignment in rotating mechanisms. The black oxide finish not only enhances corrosion protection but also reduces galling. Combined with the knurled head for non-slip handling and the Class 5g6g thread fit, this shoulder bolt delivers reliable performance in high-vibration environments, minimizing maintenance needs and downtime.

Specification Summary & Compliance

This precision metric shoulder screw features an M5x0.8 coarse thread with a Class 5g6g fit for consistent engagement.
