• Environmental compliance meeting RoHS 3 and REACH standards for global industrial use
• Optimized durability through Rockwell B79 hardness for long-term wear resistance

Professional Applications & Engineering Value

This M5 shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The 316 Stainless Steel construction provides exceptional performance in chemical processing, marine equipment, and food machinery where exposure to corrosive agents would degrade ordinary fasteners. The 15mm shoulder length with controlled diameter tolerance acts as a precise pivot or spacer, eliminating the need for additional bushings in assemblies. Combined with the coarse metric thread and hex socket drive, it ensures rapid installation and reliable load distribution in high-vibration environments like automation equipment and precision instruments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 5g6g thread fit, shoulder diameter tolerance of -0.072 to -0.01 mm, and shoulder length tolerance of 0 to 0.25 mm. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
