Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical industrial challenges, such as misalignment and corrosion in machinery. Made from 316 stainless steel with a black oxide finish, it provides superior resistance to chemicals and moisture, making it ideal for applications in marine, chemical processing, and outdoor equipment. The metric thread with coarse pitch and precise shoulder diameter tolerance (-0.072 to -0.01 mm) ensures accurate positioning in assemblies like rotating shafts and bearings, reducing vibration and wear. Its high tensile and shear strength supports heavy loads, while the knurled head enhances grip during manual adjustments. Commonly used in precision engineering, automotive, and aerospace sectors, this screw delivers reliability and longevity in industrial applications requiring strict dimensional control.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with a thread fit of Class 5g6g and shoulder diameter tolerance of -0.072 to -0.01 mm. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory conformity for global supply chains.
