Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address common industrial challenges such as misalignment and corrosion in precision assemblies. The 316 Stainless Steel material, combined with a Black Oxide finish, provides exceptional resistance to chemicals and moisture, making it suitable for marine, chemical processing, and outdoor equipment. The hex socket drive allows for high-torque applications without stripping, while the coarse pitch thread ensures rapid installation and maintains hold under dynamic loads. Its shoulder design supports rotational movement in machinery, reducing wear on connected parts and extending service life in industrial automation, robotics, and conveyor systems.
Specification Summary & Compliance
This metric shoulder screw adheres to precise dimensional tolerances, including a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm, with threads conforming to Class 5g6g fit for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial standards.
