Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in precision assembly and motion control systems. The 316 stainless steel material provides excellent resistance to chemicals and saltwater corrosion, making it suitable for marine, chemical processing, and food-grade equipment. The 40mm shoulder length acts as a precise pivot or shaft, minimizing backlash and wear in linkages, bearings, and gears. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With its hex drive and Class 5g6g thread fit, it ensures reliable, repeatable fastening in high-vibration environments like robotics, automotive jigs, and conveyor systems, delivering long-term operational stability and reduced maintenance.

Specification Summary & Compliance
