Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 316 Stainless Steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications in marine, chemical processing, and food equipment where moisture and aggressive substances are present. The hex socket drive and knurled head ensure secure handling and high torque transmission, reducing the risk of stripping during installation. The precisely machined shoulder with tight diameter tolerances acts as a pivot or bearing surface, maintaining component alignment in machinery, robotics, and automotive systems. This design minimizes wear and misalignment, enhancing the longevity and reliability of the overall assembly while meeting stringent RoHS and REACH compliance requirements.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement and dimensional accuracy. The shoulder diameter tolerance is tightly controlled at -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing consistent performance in precision applications. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), this product meets essential environmental and safety regulations for industrial use.
