Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical challenges in industrial machinery, automation, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, while the black oxide finish adds an extra layer of protection against wear and corrosion. The 30mm shoulder length acts as a precise pivot or spacer, reducing friction and maintaining alignment in rotating assemblies, such as conveyor systems, motor mounts, and robotic arms. With its coarse metric thread and Class 5g6g thread fit, it ensures quick, secure fastening even in high-vibration environments, minimizing loosening and maintenance downtime. This makes it an ideal precision shoulder bolt for applications demanding reliability, such as automotive components, packaging machinery, and electronic enclosures.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M10x1.5 coarse thread and Class 5g6g thread fit for precise tolerance. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its safety for environmental and industrial use without hazardous substances.
