Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical alignment and rotational movement challenges in industrial assemblies. The 18-8 stainless steel provides excellent resistance to rust and oxidation, making it suitable for food processing, marine, and outdoor equipment. The precision knurled hex socket head ensures secure drive engagement, reducing wear on tools and preventing stripping during high-torque installations. With a Class 5g6g thread fit and coarse M16x2mm thread, it offers quick assembly and reliable holding power in vibrating environments. The accurately machined shoulder acts as a pivot or spacer, maintaining component alignment in conveyor systems, robotics, and heavy machinery, thereby minimizing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M16x2mm coarse thread and Class 5g6g thread fit for consistent performance. Shoulder diameter tolerance is maintained between -0.072 to -0.01 mm, and shoulder length tolerance is -0.05 to 0.05 mm, ensuring precise dimensional accuracy. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and global industrial applications.
