Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical challenges in industrial applications such as machinery assembly, automotive systems, and precision instruments. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in humid or chemically aggressive settings. Its 20mm shoulder diameter with minimal tolerance ensures accurate positioning of moving parts, reducing wear and preventing misalignment. The coarse thread (M16x2mm) and Class 5g6g thread fit enable quick assembly and reliable fastening, while the knurled hex socket head allows for high-torque installation without slippage. By integrating these features, this screw minimizes downtime and enhances operational efficiency in high-stress environments.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit ensuring dimensional accuracy and interchangeability. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance from 0 to 0.25 mm, providing precise engineering fits. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industrial markets.
