Professional Applications & Engineering Value
This M16 shoulder screw is engineered to solve critical alignment and rotational stability challenges in precision applications. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and equipment exposed to moisture or chemicals. The knurled head and hex drive provide a secure grip during installation, preventing tool slippage and ensuring consistent torque application. The Class 5g6g thread fit and coarse pitch facilitate quick assembly and disassembly while maintaining a strong, reliable connection. The precisely machined shoulder diameter acts as a pivot or bearing surface, reducing wear on components and extending the service life of the entire assembly in demanding industrial settings.
Specification Summary & Compliance
This metric shoulder screw features an M16x2mm coarse thread with a Class 5g6g thread fit for standard industrial use. The shoulder diameter is 16 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is ±0.05 mm, ensuring high dimensional accuracy. The screw is manufactured from 18-8 Stainless Steel with a hardness of Rockwell B55, a tensile strength of 70,000 psi, and a minimum shear strength of 35,000 psi. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
