Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion-induced failure. The 316 stainless steel material provides excellent resistance to corrosive elements, making it suitable for applications in marine, chemical processing, and food equipment. The black oxide finish adds an extra layer of protection against oxidation while reducing light reflection. With a knurled head and hex drive, it ensures secure handling and high torque transmission during assembly, minimizing slippage. The precisely machined shoulder (20 mm diameter, 40 mm length) acts as a pivot or spacer in machinery, supporting rotational movements and reducing wear on connected components. Its right-hand metric thread and coarse pitch facilitate quick installation in automation systems, conveyor setups, and precision instruments, enhancing operational efficiency and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 for dimensional accuracy, with thread specifications including M16x2 mm coarse pitch and Class 5g6g fit ensuring reliable engagement. Shoulder dimensions are tightly controlled, with diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm, providing consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting environmental and safety standards for industrial use.
