• Optimized for coarse threading with M16x2mm right-hand thread, enabling faster assembly and reduced cross-threading risk.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered from 316 stainless steel to address critical challenges in precision machinery, automation systems, and marine equipment, where corrosion resistance and structural integrity are paramount. The 20mm shoulder diameter with controlled tolerance provides a stable bearing surface, minimizing misalignment and wear in rotating assemblies or linkages. Featuring a socket head with 10mm hex drive and knurled texture, it allows for secure tool engagement and high-torque fastening in confined spaces. The Class 5g6g thread fit and coarse 2mm pitch ensure quick, reliable installation, reducing assembly time while maintaining 70,000 psi tensile strength for heavy-duty industrial applications such as robotics, conveyors, and fixture design.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit ensuring dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 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 international industrial use.
