• Precise component alignment enabled by the 20mm diameter shoulder with tight tolerances, reducing wear and simplifying assembly.
• Secure, high-torque installation using the 10mm hex socket drive and knurled head for improved grip and reduced tool slippage.
• Durable, coarse M16x2mm thread with Class 5g6g fit for rapid assembly and robust holding power in demanding applications.
• Guaranteed quality and safety through compliance with ISO 7379, RoHS 3, and REACH standards, ensuring material and performance reliability.
• Enhanced longevity from Rockwell B79 hardness, providing excellent resistance to deformation and surface wear over time.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical challenges in precision assembly and motion control systems. The 316 Stainless Steel material provides outstanding resistance to corrosion, making it suitable for marine, chemical processing, and food-grade equipment where moisture and chemicals are prevalent. The 20mm shoulder diameter with controlled tolerances acts as a precise pivot or spacer, minimizing misalignment and bearing wear in rotating assemblies, linkages, and jigs. The coarse metric thread (M16x2mm) ensures quick and secure fastening, even in applications subject to vibration. Combined with the hex socket drive and knurled head, it allows for high-torque installation in confined spaces, enhancing assembly efficiency and reducing the risk of fastener failure in high-stress industrial environments.
